Adding initial support for HASH nodes

This PR adds initial support for HASH data nodes in libbowl.
This allows a performant key-value store lookup in a node tree.
The hashing code implements the "murmur" hash, which has shown
good performance over at [`libcuckoo`]. Currently there is no
extended hashing strategy, which should definitely be changed.

[`libcuckoo`]: https://github.com/qaul/libcuckoo

(currently a collision will cause a recursive re-alloc)

Some of the type-level hacks also begs the question if a PAIR
data node might be warranted, even though it would break the
simple design around bowl->data.
