feat: add filtering to manager ui

[ngtv2409]

Add new key f to filter parsers by status.

I am thinking instead of prompting for the filter mode, just cycle between all, warn, fail, ok.

That's actually my first thought but I thought that being able to specify different status at the same time would be useful, though maybe it's not that useful. So I guess I'll do that then.

It's much faster to just repeatedly press f. Another thing we can add maybe is to sort the list of languages based on the status in the all mode. That would have the same effect as the warn,ok filter?

I think that's a good point considering the use case of this.

[tunaflsh]

There are a few more edge cases.

• When you are in the ok mode and remove a language, and want to reinstall it you will have to cycle back to all or fail and search for the language.
• Also I think it makes more sense to have a mode installed instead of ok which should include both ok and warn. Because both are technically installed, but the other is just missing dependencies.

So what I propose is to keep the current list of languages and the order fixed unless your reopen the UI or press f. And have four modes: all, installed, warning, missing. Also, I think instead of printing "None" just cycle to the next mode.

[ngtv2409]

good ideas.

I did a lot of refactoring.

Changes

• The list of languages is persistent until you refresh. So uninstalling a language from filtre mode installed doesn't make it disappear.
• All buffer keymaps sync the status as before, but now user commands like TSInstall will also sync to the buffer.
• Removed _act (BREAKING).
• The filter cycle skips duplicating modes. For example, if the installed mode has only warnings pressing f will skip straight to the missing mode. The normal cycle is all -> installed -> warning -> missing.

@romus204 would you take a look?
