update tgtg; Add local token store procedure

[Dielee]

Add local token store procedure to prevent repeated login emailing from tgtg.

Awesome, thanks ❤️

One thing that crosses my mind when working on that from the other side (see https://github.com/MaxWinterstein/tgtg-python), what happens when I turn off the bridge for longer than the access_token_lifetime? I guess this case is not handled within tgtg and might end up in an exception loop?

I am currently trying out what happens after expiration.
Possibly a new authorization can be done with the refresh_token.

Please wait with commiting until this case is safe!

Great, let me know when it's done 😀

So, refreshing token while running tgtg bot is working.
If the application is not running, the first loggin will always be done by credentials.

will have a look and test in detail later.
