More performance improvements:
- Optimize lookup of first 4096 codepoints
- Avoid overwrite lookup if no overwrites are set
## 2.4.1
- Improve general performance!
- Further improve performance for ASCII strings
*You should really upgrade - it's much faster now!*
## 2.4.0
- Improve performance for ASCII-only strings, by @fatkodima
- Require Ruby 2.4
## 2.3.0
