Initial Release!

This module implements a common interface to many different secure hash and message digest algorithms. Included are the FIPS secure hash algorithms SHA1, SHA224, SHA256, SHA384, and SHA512 (defined in FIPS 180-2) as well as RSA’s MD5 algorithm (defined in Internet RFC 1321).

SHA1 and MD5 algorithms are not currently supported by the CircuitPython module, but constructors/sub-modules are included in the library to retain backwards-compatibility with the CPython3 hashlib module's available algorithms.
