 Determines the monospace display width of a string in Ruby. Useful for all kinds of terminal-based applications. Implementation based on [EastAsianWidth.txt](https://www.unicode.org/Public/UNIDATA/EastAsianWidth.txt) and other data, 100% in Ruby. It does not rely on the OS vendor (like [wcwidth()](https://github.com/janlelis/wcswidth-ruby)) to provide an up-to-date method for measuring string width.
