Add FSRS support

[rwmpelstilzchen]

Now with FSRS built into Anki (23.10+), I think adding FSRS simulation is worthwhile. If I understand correctly, currently the simulation depends on using the traditional Anki algorithm (based on SM-2) for making predictions

Thank you for all the great work you’ve done with this add-on ^_^

I recently created a request on fsrs github page for incorporation of simulator into anki.
I got this response from LM Sherlock recently " The built-in FSRS crate has provided function to simulate the learning process with FSRS.

https://github.com/open-spaced- repetition/fsrs-rs

So I recommend submitting a request in https://forums.ankiweb.net/ "

It seems the backend coding has been done to allow for export of data for simulator to work if the current one is updated.
The request that i logged:
open-spaced-repetition/fsrs4anki-helper#322

The code that was updated:
open-spaced-repetition/fsrs4anki-helper#322

@giovannihenriksen @glutanimate if you could please work on this update. It would be much appreciated.
Thank you.

Voicing my support!

Whether this add-on can take in FSRS data, or a GUI is built in to Anki to provide the same functionality, I agree it would be highly useful!

Thanks everyone.
