Improved corrections tables

[jquast]

• Improved** wcstwidth()_ with new zeroer, narrow_wider, and narrow_zeroer Corrections_.

• Such as standalone fitzpatricks, 🏼🏽🏾🏿 etc are width 0, 'narrower' only covered "usually wide characters are narrow", we need additional 'zeroer' case for terminals like this.

• PUA codes ignored

• surrogate pairs ignored
