Closes #198.

Closes #155, Should Combining characters of Category 'Mc' be width 1? **Yes**.

As I wrote then, "Probably the largest obstacle has been finding 1 or 2 Terminal emulators that correctly display languages that include Mc characters.". I felt it would be too progressive, but I have since found some TE's capable of measuring *and rendering* complex script like Devanagari correctly. Some may agree by cursor positions can agree, I need to also see the font legibly! So I hope that with this change, and ucs-detect, we can detect which TE's are missing this fix.

I expect ucs-detect results for sanskrit-based languages to improve in next release with this update.

CLoses #133 and #154.

This decreases general performance by ~10% for complex CJK/combining and emoji strings.

- Regional Indicator pairs measured as one 2-cell flag; unpaired RI measured individually
- Fitzpatrick skin tone modifiers are zero-width when following an emoji base, Narrow when "standalone"
