Playback speed adjustment: finer adjustments

[tyrossel]

Hello, thank you for this app !
As stated in the original issue #274 , musician and dancer use this feature to adapt the tempo to their needs. A list of pre-selections every 0.25% is not enough, as I regularly find myself adjusting tempo by smaller steps.
Adding slider in the existing popup window would be a nice interface for that.
As an example, a similar popup is implemented in AntennaPod:

Hi there!

This looks quite achievable, #376 laid the groundwork to alter playback speed (we now have a method to do that).

Actually, I have seen a really similar UI before:

Checking AntennaPod's source code they achieve it fairly easily:

• The seek bar XML
• The dialog holding the seekbar
• The logic that glues all together

We wouldn't need to create a special Java file, only to change:

mediaBrowser.setPlaybackParameters(new PlaybackParameters(currentSpeed));

from PlayerControllerFragment.java with

mediaBrowser.setPlaybackParameters(new PlaybackParameters(bind.playbackSpeed.getProgress()));

Of course the preferences file must be updates accordingly, but it looks fairly straightforward.

@eddyizm can you convert this into an issue?

It's a nice QoL feat and a great fit for the good-first-issue tag.
