Integrate SponsorBlock

### What problem does this address?

Egregious/repetitive/boring ad breaks that are difficult to skip: (skip forward 30s, back 10s). Spotify podcast ad breaks are easier to skip because they have a separate seek bar that can be immediately dragged to the end to skip ads.

### What is your proposed solution?

Integrate with SponsorBlock to allow community tracking of ad breaks.

In the app offer automatic skipping of ads, or a skip button to simplify and speed up the skipping process.

### Did you search for existing feature suggestions?

No files or tests are named. Start by locating the Android playback and networking entry points, then review how seeking and playback controls are implemented; done means SponsorBlock ad-break data can support reliable automatic skipping or a user-triggered skip action.
