Using "second-mate"

[mauricioszabo]

Second-mate is basically the Atom's "First Mate" (TextMate helpers) but converted to use vscode-oniguruma instead of node-oniguruma.

This PR adds support for second-mate as the TextMate tokenizer. For related PRs, see here: pulsar-edit/second-mate#1

We may need more tests on this code, and also fix bracket-matcher (that it needs first-mate - maybe even use Pulsar's tokenizer instead)

Excited to see how the tests turns out on this one

I should've mentioned this on the second-mate repo, but: if we can replicate the OnigRegExp API with only OnigScanner, it'd be great if we could do that in second-mate and export both OnigRegExp and OnigScanner from second-mate itself — just to prevent having to rewrite all these usages.

@savetheclocktower yeah, that's a good idea...

Unfortunate, it's too late now 😆

I honestly didn't like the errors the CI reported...
