IDNA refactor names (#130)

* I managed to find that I renamed a namespace and class as the same, so I fix that here

* Made IDNA code point status a bit more efficient

* Compressed IDNA table a little more by storing code points with values <= 0xffff as char16_t

* Fixed IDNA table generator script
