Initial implementation of the MCF pseudo-format as described at: https://passlib.readthedocs.io/en/stable/modular_crypt_format.html
Note that MCF is less a specification than an ad hoc set of conventions.
As MCF lacks the kind of rigidly specified sizes of its various components, a heapless
no_std
implementation isn't really possible like it is with the PHC format, and so this implementation has a hard dependency onalloc
(though it should be possible to extract analloc
-free reference type which borrows from its input).
