Infinite notes mode

[samouri]

summary
Taking inspiration from sightreading.training, we should create a mode with infinite notes for practicing reading the staff.

Do you mean using sheet hero and spawning random notes?

@EloxZ: Yes, I meant sheet hero mode. I've actually already begun work on a similar task ~8mo ago, but caught up in a new job and never got it to a good state. You can check out the prototype here at https://sightread.dev/training/phrases. The code starts here.

This mode is a "phrase generator" (generates 30s snippets for practice), and scores you on it. It has an audio backing tracking to make it more fun. It was so long ago now that I don't remember what it was missing...maybe just testing and more parameters to configure. Feel free to try it out and let me know what you think! The phrase generation is a bit different than what sightreading.training offers (highly configurable infinite note generation), so feel free to work on that separate from the phrase training.

Not to discourage you from this, but I think the issue you opened up #110 would be a great first project. A recording icon could be neatly added to the "freeplay" mode, and I think it'd be really neat to be able share a recording (either mp3, or even the ability to replay the recording within sightread!).
