This library was non-functional unless used with the micropython-lib
pure-Python implementation of hashlib, even if the device provides
sha1 and sha256.
This updates hmac to be significantly more RAM efficient (removes the
512-byte table), and functional with the built-in hash functions.
The only unsupported function is "copy", but this is non-critical, and now
fails with a NotSupportedError.
