Make the module hashlib-compliant

[varunkumar]

mmh3 is currently not hashlib-compliant. This makes it challenging to use it as a replacement for md5 or other cryptographic hashes. A wrapper can be built to make this module hashlib-compliant. One should be able to use the module as hashlib.md5.

update() -- update the current digest with an additional string
digest() -- return the current digest value
hexdigest() -- return the current digest as a string of hexadecimal digits
intdigest() -- return the current digest as an integer
copy() -- return a copy of the current mmh3 object
reset() -- reset state

Thank you for your ideas.

I'm really interested in the proposal, so I'll try to implement a hashlib-compliant interface in the next update (hopefully in the first half of April).

The implementation of this feature has been (experimentally) done in version 4.0.0.
