Credit

This implementation is influenced in part by https://github.com/tilinna/z85

Enhancements

This implementation does not require the caller to allocate storage buffers before calls to Encode or Decode.

This implementation provides functions to pad inputs to a length that is a multiple of 4; a complementary trim function is also provided.
