[FEATURE] Add jump forward/back X seconds for podcasts

[jerefrer]

Hi there, thanks for this amazing tool and all your work!

I'm often working on repetitive tasks while listening to podcasts. I already use the notch to play/pause podcasts when I really need to focus without distraction and then start it again. But often my attention drifts from listening to my task and want to listen again to what has just been said. So since I already have the habit of going to the notch for pausing, I though it would be the best place to also easily rewind a little bit when needed.

Therefore when listening to a podcast I'd be very happy to have a "go back/forward 15 seconds", or 30, or why not be able to define a custom duration.

Maybe both prev/next and rewind/forward button sets could be displayed at the same time, or if the space is too tight then maybe replace prev/next by rewind/forward if the track is longer than a given duration (30min?).

What do you think?
