Is hat-trie optional or mandatory?

[cmb69]

README.md claims that the HAT Trie library is optional, but config.m4 fails without it, and while config.w32 does not fail, the build won't succeed because the code relying on hat-trie is unconditionally compiled.

So, is hat-trie optional or mandatory?

The hat-trie library is an optional dependency.

Thanks for the clarification! I'll provide a PR soonish.
