Oauth refresh on request

[zeitmeister]

This fix should update so that for every request to ytmusic the code checks if the access token needs refreshing and refreshes it if that's the case.

However, the headers object are updated on every request, regardless if the token needs refreshing or not. This is probably not cpu heavy by any means but should perhaps be looked at in another iteration. or when i have more time...

You can easily fix this by extending __init__ so that we know if this is an is_oauth instance (set a new instance variable like is_browser_auth). Then simply check for the value of that variable. Also you could simply call load_headers directly since we know then that it's an oauth instance.

Thank you for your comments. I think i managed to come up with something that works better. I also updated the prepare_headers function in headers.py so that they use the same YTMusicOAuth instance.

I think this is pretty close to a good solution, although still some optimizations to be had

I hope that the last fix makes the test run. I also don't know why these commits with merges keeps coming. they seem to be from another fork or something. git wouldn't let me push if i didn't pull stuff that i didn't even change in the first place..

anyway, thanks again for your comments. I think they really improved the funcionality.

This does it. Thanks for the persistence. No worry about the commits, they get squashed anyway
