Show Custom Data information (e.g. FSRS scheduling data like Stability)

[hugomarins]

Nowadays, anki has a Custom Data shown on browser Card Info. It has content stored there when using FSRS Scheduler (namely, Difficulty and Stability, among other data). It would be very nice if this add-on could also have CustomData as one of the data that we may show in the sidebar.

FSRS seems to store its values in card.custom_data, see ankitects/anki@31b7464

custom_data is just some json, e.g. the fsrs helper add-on reads the custom data for the browser like this https://github.com/open-spaced-repetition/fsrs4anki-helper/blob/09e03277c340716074155bdba1699adc88dff768/browser/custom_columns.py#L111

This should allow you to add it yourself until i find time to update the addon.
