Convert to a hash representation

Description

Provides a data type (SHA256) for efficient memory representation of a sha-256 hash value, together with helper functions for converting to and from that value. This module is intended to be imported qualified as SHA256.

Some nomenclature:

Hashing calculates a new hash value from some input. from takes a value that represents an existing hash.
Raw means a raw binary representation of the hash value, without any hex encoding.
Text always uses lower case hex encoding
