refactor: parser & cloze patterns

[st3v3nmw]

Updating the parser to use peggy has slowed the plugin drastically (See #1115, #1111, & #1110). This change refactors the parser to one written by hand compared to an auto-generated one. I think this is the better approach for performance reasons & it's sad that we have to undo all the work that went into #1012.

I've tried to replicate the existing behavior as closely as possible with the new parser including the multiline cards with spaces introduced in #1012.

On the brighter side, we've switched parsing of cloze cards to use @MotaOcimar's clozecraft package from #943.
