wordpaste: Microsoft Word paste cleaned before Quill sees it, equations land in the formula blot

[smrifat1411]

Quill 2 has no paste prop, so this subclasses the clipboard module: the raw clipboard HTML from Microsoft Word, LibreOffice Writer, Google Docs, Outlook or Excel goes through wordpaste first, and Word equations come out as a span that one matcher maps onto Quill's own formula embed (KaTeX renders it).

Live example with the six lines of wiring: https://smrifat1411.github.io/wordpaste/examples/quill.html

What it does: real nested lists with the original numbering, tables and alignment kept, colours and fonts dropped, Word and LibreOffice equations editable. 4.3 kB gzipped, zero dependencies, MIT: https://github.com/smrifat1411/wordpaste
