Spell check underline ignores tabs in text

[beaswag]

the red underline that appears under words the spellcheck doesn't like completely ignores tabs in the original text, resulting in the underline not lining up with the word.

I think the problem is that the Tab offsets the word and the linter doesnt take that into account at all

This is kind of a hard one to fix due to how tabs and spaces are treated as the same symbol there.

If anyone would like to try a pr, you would need to somehow keep tabs at

and account for them all the way to
https://github.com/YarnSpinnerTool/YarnEditor/blob/master/src/js/libs/spellcheck_ace.js#L126

ace editor kind of makes this extra funky too.I couldnt figure out a clean way to fix it, but would welcome one :)
