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.

 * Create PRs that cover only **one specific issue/solution/bug**. Do not create PRs that are huge monoliths and could have been split into multiple independent contributions.
 * NewPipe uses [NewPipeExtractor](https://github.com/TeamNewPipe/NewPipeExtractor) to fetch data from services. If you need to change something there, you must test your changes in NewPipe. Telling NewPipe to use your extractor version can be accomplished by editing the `app/build.gradle` file: the comments under the "NewPipe libraries" section of `dependencies` will help you out.
 
-### Kotlin in NewPipe
-* NewPipe will remain mostly Java for time being
-* Contributions containing a simple conversion from Java to Kotlin should be avoided. Conversions to Kotlin should only be done if Kotlin actually brings improvements like bug fixes or better performance which are not, or only with much more effort, implementable in Java. The core team sees Java as an easier to learn and generally well adopted programming language.

 ### Creating a Pull Request (PR)
 
 * Make changes on a **separate branch** with a meaningful name, not on the _master_ branch or the _dev_ branch. This is commonly known as *feature branch workflow*. You may then send your changes as a pull request (PR) on GitHub.

@@ -103,10 +104,10 @@ You can install NewPipe using one of the following methods:
 We recommend method 1 for most users. APKs installed using method 1 or 2 are compatible with each other (meaning that if you installed NewPipe using either method 1 or 2, you can also update NewPipe using the other), but not with those installed using method 3. This is due to the same signing key (ours) being used for 1 and 2, but a different signing key (F-Droid's) being used for 3. Building a debug APK using method 4 excludes a key entirely. Signing keys help ensure that a user isn't tricked into installing a malicious update to an app. When using method 5, each APK is signed with a different random key supplied by GitHub Actions, so you cannot even update it. You will have to backup and restore the app data each time you wish to use a new APK.
 
 In the meanwhile, if you want to switch sources for some reason (e.g. NewPipe's core functionality breaks and F-Droid doesn't have the latest update yet), we recommend following this procedure:
-1. Back up your data via Settings > Content > Export Database so you keep your history, subscriptions, and playlists
