Rather than accept boolean parameters, the options are now in a struct passed to the function.

This means

zf.rank(string, token, false, false);
zf.rank(string, token, false, true);

Is now written as

zf.rank(string, token, .{});
zf.rank(string, token, .{ .plain = true });

This makes the default case simpler, and also makes the boolean parameters clear at the call site.

The case_sensitive parameter was also named to to_lower for more clarity. See the library docs for more information.

Other Changes

• The UI was completely rewritten to use libvaxis instead of my own custom terminal rendering code.
• The env variable ZF_PROMPT no longer supports terminal escape sequences. It was difficult to support this when rewriting to use libvaxis. Support for this feature may return in the future if there is interest.
• Adds an option to zig build to compile as a PIE executable. This should be useful for package mainainers. Use zig build -Dpie to enable this option
  • This was contributed by @tranzystorekk (their first contribution) in https://github.com/natecraddock/zf/pull/64. Thanks!
• Zf no longer does unicode normalization of the input.
