zf 0.6.0

This release is focused on small optimizations, refactors, and using zf as a library. Because zf is now packaged as a Zig library, it makes sense to switch back to semantic versioning which makes this version 0.6.0 rather than 0.6. This release also updates the source code to support Zig 0.10.0.

While refactoring zf to be more easily consumed by a library, I designed the library to require zero allocations and be passed external slices of memory. Alongside this I also added a restriction to zf as a cli tool. The number of space-separated tokens in the query is now limited to 16. This seems like a safe upper limit, but can be raised if needed.

See the changelog for more details.
