Use AGPL instead of GPL

As this is server-side code, I think that the code would be better protected under the AGPL instead of the regular GPL.

@J-8 what do you say?

Why you think that?

👍 I think @ainola is right here

If you do end up changing the license, here's an example to get all of the code contributors to agree to a change: mpv-player/mpv#2033

Thanks @ainola for pointing that out! I completely agree.

I also accept the AGPL :)
