0.12.0: Optimizations

This release improves speed and memory efficiency. A couple techniques were used:

• Character case checks first check ascii before doing the more expensive grapheme checks (which require heap allocations).
• Delimiter only splits get a dedicated path in the split method.
• The case of characters is computed upfront in a bitmask before checking individual boundary conditions in split. Built-in boundaries get a custom implementation built on top of this bitmask.
