Handle errors spanning multiple tokens

[with-heart]

This PR resolves #144 by creating a new function that checks whether each token is within the range of an error (e.character to e.character + e.length). Checking the range produces the correct results (T[Key] is highlighted as an error):

This function replaces findTokenFunc only when handling errors (lsp responses + queries still use findTokenFunc).

I also added isTokenWithinErrorRangeDebug which is similar to findTokenFuncDebug for any future debugging needs.

The accurateErrors fixture from remark-shiki-twoslash is failing, but I'm not entirely sure why. After removing all the noise, here's the diff:

- <data-lsp lsp='const todo: Readonly&lt;Todo>' >todo</data-lsp>.<data-err><data-lsp lsp='(property) title: any' >title</data-lsp></data-err>
+ <data-lsp lsp='const todo: Readonly&lt;Todo>' >todo</data-lsp>.<data-lsp lsp='(property) title: any' >title</data-lsp>

It shows that it's not rendering title in todo.title = 'Hello' as an error, but if I drop that fixture in a twoslash block in a local app using these these changes (with remark-shiki-twoslash), title is highlighted just fine:

Any ideas?

Oof, not sure when I'll find time to dig into this properly - this section of code is super gnarly and not an area I fully grok anymore
