Allow youtube connector to get data from Youtube Music

[Boelensman1]

Describe the changes you made
Add a track info getter that uses youtube music to get its information. This information seems to be more reliable than the info in the description. Downside is that this getter has to make a request, which takes a bit, so there's a bit more delay before the scrobbler finds the information. It does cache all requests it has made already, so this is only the first time, as long as the user doesn't restart their browser.

At least in my experience this getter seems to me more reliable than the ones based on description/title, but I'm not sure how to verify this as it might depend greatly on the type of music you listen to. It's not perfect regrettably, for example it might swap names around compared to the most common value in Last.fm, eg. "Fireboy DML & Asake" becomes "Asake & Fireboy DML".

I also added an option to only scrobble videos that are recognised by yt music as a music video, which seems to work quite well.

I can only write in English so someone else will have to translate this option to the other locales.

Looks interesting. I can see a few potential issues, but I need to spin it up to confirm, I think I should have a bit of time tomorrow.
The addition of a request shouldn't be a massive issue I think, we already have a couple of connectors that do this.
Given that this is a pretty substantial change to the most used connector I'd definitely like for other organization members to weigh in before it is merged.

I can also see that this getter should definitely be disableable in settings.
For instance, youtube music tags will usually be a regression for those that prefer scrobbling untranslated titles without having their youtube/ytm interface actually be in that language.

As requested, added an option to disable the getter, it works independently from the option to only scrobble if yt music detects it as a music video. So the behaviour is as follows:

Both options enabled or only the getter enabled:
Getter makes request and runs as usual, returns artist & track (if found)

Only 'scrobbleMusicRecognisedOnly' enabled:
Getter makes request to fill the cache to allow the check on if youtube music thinks this is music but returns an empty object so next getter is run

Neither option is enabled:
Getter immediately returns empty object, no request is made.

Hi, do you want to add some of the extra logic that you added later on added to this PR before it is merged, or do you want it to be merged as is?

[Boelensman1]

I can't really add the extra logic as that's all about returning multiple possibilities for matches which isn't useful for this project (yet?), so it can be merged as is!
