3.2

Added

• sys_string can now be normalize()-ed to NFC and NFD.
• It is now possible to use ICU instead of internal data/code for case conversion, grapheme
  iteration and normalization. This makes those operations a tiny bit slower but saves
  ~100kB in a final executable if you use all of them.

Changed

• This library is now header only
• Speed improvements to case conversions, case insensitive comparisons and grapheme iteration.

Fixed

• Addressed some false positive sanitizer warnings.
