perf: cache getfullargspec on the hot matching path

getfullargspec is called for every validator/formatter/conflict-solver
invocation via loose.call. Its result depends only on the callable, and
those callables are stable singletons for a Rebulk instance's lifetime,
so the introspection is fully redundant across matching calls.

Wrap it in an unbounded lru_cache: ~11% faster repeated parses for a
one-line change. The set of distinct callables is small and bounded,
callables are hashable, and getfullargspec is a pure function of its
argument, so caching by identity cannot change behaviour.

closes #77
