[FEAT] Per station volume memorization.

[Scary-Guy]

Is your feature request related to a problem? Please describe.
Many stations vary in their volume output with some being way louder than others.

Describe the solution you'd like
It would be very beneficial if the user could set an output level while the station is playing, and then hit a key to set the level for that station only.

This could also be useful in the context of different station genres. For example, sometimes a station is more suited to background ambiance so maybe the user would want that volume lower. Another station might be more geared toward dance/nightclub music which the user might want louder.

Describe alternatives you've considered
Volume normalization could also work for this I guess, but I kinda don't want to mess with it and in my head this seems much better as it gives the user more control. However, there should also be an option in settings/by keybind to turn off the per station volume as well and just use the overall volume for this use case.
