This PR adds types and utility functions for manipulating nibbles (4-bit value arrays). It is specifically to support a new package, statetrie, which will use Nibbles and their associated utility functions.
The statetrie is designed to have keys with sequences of 4-bit bytes. A statetrie with 16-ary branch nodes has smaller proofs than a full byte (256-ary).
