charr: String Processing Reimagined for 'ALTREP' Strings

An experimental fork of 'stringr'. The functions and semantics are the same, apart from differences between 'ICU' and Unicode versions, but everything is optimized around 'ALTREP' strings (custom high-performance string storage), allowing for faster and more efficient operation.
