WIP: integrate onBackPressed flow as callback

This sets up a little JavaFlow wrapper so we can register callbacks on
the back press flow in Java-land.

Inspired by one of the answers in
https://stackoverflow.com/questions/60605176/kotlin-flows-java-interop-callback

Kotlin generates default interface instances, but only if
`-Xjvm-default=all` is set in the compiler flags. The Java IDE
would propose using a lambda, which would fail because the kotlin
compiler would not generate the right ABI without that flag.

  3. Update via F-Droid. This is the slowest method of getting updates, as F-Droid must recognize changes, build the APK itself, sign it, and then push the update to users.
  4. Build a debug APK yourself. This is the fastest way to get new features on your device, but is much more complicated, so we recommend using one of the other methods.
  5. If you're interested in a specific feature or bugfix provided in a Pull Request in this repo, you can also download its APK from within the PR. Read the PR description for instructions.
