Add Argon2Kdf and enable parameters in db settings

Note: This implementation is not yet connected to the
database itself and will corrupt existing kdbx3 db's.

* Implemented memory and parallelism parameters for Argon2Kdf
* Using libargon2; libsodium does not support Argon2d algorithm
* Moved basic rounds parameter into Kdf class
* Reimplemented benchmark algorithm; previous was utterly broken
