Support cards/day limit in FSRS optimizer

[dae]

open-spaced-repetition/fsrs-rs#141

We need to expose learn_limit and review_limit in the GUI, and make it a union with the daily cost setting: open-spaced-repetition/fsrs-rs#141 (comment)

@abdnh another one for you if you're interested

I got confused by "optimizer" in the title. I assume the issue is about the frontend part of #3075. In addition to exposing the simulation inputs in the GUI, we need to graph the results (probably in a popup window).

I'll need to defer to @L-M-Sherlock on this, as the simulator has been changed a few times. When writing this ticket, I was under the impression we'd just need to expose those two values, but I'm not sure how they fit in now / how things will change if we add a built-in graphing simulator in the future.

[L-M-Sherlock]

These two values should be exposed in the built-in simulator in the future.

[dae]

So, to confirm, you're saying there's nothing we should do for now?

[L-M-Sherlock]

Yeah. The current finding optimal retention feature doesn't require it.

This issue could be closed.
