- Voice messages can be scrubbed (i.e. seeked to) even when they have not been played yet..
- The progress bar is displayed also when paused.
- Multiple voice messages can keep their state when paused.
- Tries to adhere as much as possible at the detailed "green cursor" behavior in the story (but might not be 100% compliant).
Story: https://github.com/vector-im/element-meta/issues/2113
Change to `MediaPlayer` API to allow waiting for the player to be in a ready state.
This is needed in order to perform some tasks (e.g. read the media duration, seek) after changing the media file.
* Show voice message preview player progress
* Update screenshots
* Fix test
* Some nits over mediaplayer stuff
