FEAT(positional-audio): Add searchInBuffer() and findPattern()

searchInBuffer() searches for the specified pattern in the specified buffer. "?" is used as wildcard.

findPattern(), given a start address and the size of the area, reads memory in chunks of 32 KiB.

It stops when a match is found, the end is reached or an error is encountered (peek() fails).

There's also an overload which iterates through the specified module's readable regions.
