Playback skipping around randomly

Original report from 5359958-zen:

> My app is sometimes skipping around different parts of the episode I am listening to randomly. This has been happening for a couple of days. My phone is in my pocket listening on a Bluetooth headset and the episode will just all the suddenly jump to a different time stamp. Phone is still locked with screen off in pocket, I have ruled out accidental touches.

### Update
The most common cause of this is what was suggested in https://github.com/Automattic/pocket-casts-android/issues/157#issuecomment-1251847030, basically that dynamic ads within an episode are changing as an episode is being streamed and that's causing the jumps. If this is true then that means:
1. **Downloading the episode avoids the issue** (let us know if you have the issue with a downloaded episode) and
2. The issue is more likely to occur if you take a break in listening to the episode (if you take a 2 week break in the middle of listening to an episode, there is a much higher chance that a dynamic ad will change compared to if you listen to an episode straight through).
3. The issue is more likely to occur the longer an episode is and the further into the episode you are
