[Feature Request] Add Spaced Repetition to tasks

Right now, in the Quire professional plan is it possible to set up a task, with a start and end date, and also set how many rounds, laps or repetitions you need for the task to be done.

But sometimes, you need to master a certain topic, or you are a student or are preparing a speech. When you need a more suitable schedule for achieving long-term memory, Spaced Repetition is the way to go.

There you have the highly-regarded Supermemo SM-2 interval algorithm: https://www.supermemo.com/en/archives1990-2015/english/ol/sm2

I would like to propose to the Quire team to implement this repetition method in tasks.

Please, do let me know your thoughts.
