update dependencies, refactor config loading to async

This removes a lot of very outdated dependencies, updates many to
their modern (usually promisified) versions, and updates (or removes)
code to account for the change.

Several dependencies have been completely removed, and others a bit
shuffled around, so that the node_modules folder can be bundled somewhat
more optimally than it would have otherwise.

+# Changers Lorgs!
+
+## 1.0
+
+Full rewrite.  Essentially a brand new module.
+
+- Return a promise instead of taking a callback.
+- Use native `fs.mkdir(path, { recursive: true })` when available.
+- Drop support for outdated Node.js versions.  (Technically still works on
+  Node.js v8, but only 10 and above are officially supported.)
+
+## 0.x
+
+Original and most widely used recursive directory creation implementation
+in JavaScript, dating back to 2010.

-# usage
+## mkdirp.manual, mkdirp.manualSync
+
+Use the manual implementation (not the native one).  This is the default
+when the native implementation is not available or the stat/mkdir
+implementation is overridden.
+
+## mkdirp.native, mkdirp.nativeSync
+
+Use the native implementation (not the manual one).  This is the default
+when the native implementation is available and stat/mkdir are not
+overridden.
+
+# implementation
+
+On Node.js v10.12.0 and above, use the native `fs.mkdir(p,
+{recursive:true})` option, unless `fs.mkdir`/`fs.mkdirSync` has been
+overridden by an option.
+
+## native implementation
+
+- If the path is a root directory, then pass it to the underlying
+  implementation and return the result/error.  (In this case, it'll either
+  succeed or fail, but we aren't actually creating any dirs.)
+- Walk up the path statting each directory, to find the first path that
+  will be created, `made`.
+- Call `fs.mkdir(path, { recursive: true })` (or `fs.mkdirSync`)
+- If error, raise it to the caller.
+- Return `made`.
+
+## manual implementation
+
+- Call underlying `fs.mkdir` implementation, with `recursive: false`
+- If error:
+  - If path is a root directory, raise to the caller and do not handle it
+  - If ENOENT, mkdirp parent dir, store result as `made`
+  - stat(path)
+    - If error, raise original `mkdir` error
+    - If directory, return `made`
+    - Else, raise original `mkdir` error
+- else
+  - return `undefined` if a root dir, or `made` if set, or `path`
+
+## windows vs unix caveat
+
+On Windows file systems, attempts to create a root directory (ie, a drive
+letter or root UNC path) will fail.  If the root directory exists, then it
+will fail with `EPERM`.  If the root directory does not exist, then it will
+fail with `ENOENT`.
+
+On posix file systems, attempts to create a root directory (in recursive
+mode) will succeed silently, as it is treated like just another directory
+that already exists.  (In non-recursive mode, of course, it fails with
+`EEXIST`.)
+
+In order to preserve this system-specific behavior (and because it's not as
+if we can create the parent of a root directory anyway), attempts to create
+a root directory are passed directly to the `fs` implementation, and any
+errors encountered are not handled.
+
+## native error caveat
+
+The native implementation (as of at least Node.js v13.4.0) does not provide
+appropriate errors in some cases (see
+[nodejs/node#31481](https://github.com/nodejs/node/issues/31481) and
+[nodejs/node#28015](https://github.com/nodejs/node/issues/28015)).
+
+In order to work around this issue, the native implementation will fall
+back to the manual implementation if an `ENOENT` error is encountered.
+
+# choosing a recursive mkdir implementation
+
+There are a few to choose from!  Use the one that suits your needs best :D
+
+## use `fs.mkdir(path, {recursive: true}, cb)` if:
+
+- You wish to optimize performance even at the expense of other factors.
+- You don't need to know the first dir created.
+- You are ok with getting `ENOENT` as the error when some other problem is
+  the actual cause.
+- You can limit your platforms to Node.js v10.12 and above.
+- You're ok with using callbacks instead of promises.
+- You don't need/want a CLI.
+- You don't need to override the `fs` methods in use.
+
+## use this module (mkdirp 1.x) if:
+
+- You need to know the first directory that was created.
+- You wish to use the native implementation if available, but fall back
+  when it's not.
+- You prefer promise-returning APIs to callback-taking APIs.
+- You want more useful error messages than the native recursive mkdir
+  provides (at least as of Node.js v13.4), and are ok with re-trying on
+  `ENOENT` to achieve this.
+- You need (or at least, are ok with) a CLI.
+- You need to override the `fs` methods in use.
+
+## use [`make-dir`](http://npm.im/make-dir) if:
+
+- You do not need to know the first dir created (and wish to save a few
+  `stat` calls when using the native implementation for this reason).
+- You wish to use the native implementation if available, but fall back
+  when it's not.
+- You prefer promise-returning APIs to callback-taking APIs.
+- You are ok with occasionally getting `ENOENT` errors for failures that
+  are actually related to something other than a missing file system entry.
+- You don't need/want a CLI.
+- You need to override the `fs` methods in use.
+
+## use mkdirp 0.x if:
+
+- You need to know the first directory that was created.
+- You need (or at least, are ok with) a CLI.
+- You need to override the `fs` methods in use.
+- You're ok with using callbacks instead of promises.
+- You are not running on Windows, where the root-level ENOENT errors can
+  lead to infinite regress.
+- You think vinyl just sounds warmer and richer for some weird reason.
+- You are supporting truly ancient Node.js versions, before even the advent
+  of a `Promise` language primitive.  (Please don't.  You deserve better.)
+
+# cli
 
 This package also ships with a `mkdirp` command.
 
 ```
+$ mkdirp -h

-               permission string.
+  -m<mode>       If a directory needs to be created, set the mode as an octal
+  --mode=<mode>  permission string.
+
+  -v --version   Print the mkdirp version number
 
+  -h --help      Print this helpful banner
+
+  -p --print     Print the first directories created for each path provided
+
