Description of the changes in your PR

Hi. I have been brutally stabbed too many times to count by CheckStyle. In my dying breaths... I bring you per-category skip settings and "un-skipping" of segments.

• When within a segment, added an option to manually skip. This is controlled by "Show manual buttons"
• Added ability to un-skip auto skipped segments for 5 seconds after the segment elapses
• Added a toggle to allow "rewinding" into segments (ex. double tap to re-watch skipped segment will actually allow you to watch the segment). This is controlled via "Rewind pauses skipping"
• Per-segment category skip options (Automatic, manual, highlight only). This is controlled by "Skip Mode" from within SponsorBlock Categories

Before/After Screenshots/Screen Record

Settings

The default settings are:

• Show manual buttons : on
• Rewind pauses skipping: on
• SponsorBlock Categories: Skip Mode defaults to "Automatic", a.k.a mimicing the existing behavour of the Enable toggle

Extra notes

• Tested on Android 14 (LineageOS 21)
• Buttons may be offset weirdly when rotating the device.
  • I am pretty sure is an upstream issue (the underlying view/container does that)
• Why are you creating a whole new button for an icon when you can replace it all with:
  • app:drawableLeftCompat="@drawable/ic_previous" android:drawableTint="@color/white"
  • SDK drawableTint requires SDK 23 (we are on 21)
• Possibility of not vertically centered skip/un-skip buttons, they are however aligned with the play button... which I just found out also isn't centered

APK testing

The APK can be found by going to the "Checks" tab below the title. On the left pane, click on "CI", scroll down to "artifacts" and click "app" to download the zip file which contains the debug APK of this PR. You can find more info and a video demonstration on this wiki page.
