This commit adds a new process method to all Decoder subclasses which do what to_utf8 used to do, and allows callers to customize the handling of individiual UTF-8 code points through a callback. Decoder::to_utf8 now uses this API to generate a string via StringBuilder, preserving the original behavior.
