Fix inconsistencies between the hooks

Fix a long-standing bug with relrn cards in review hook

Before this update, cards in the relearning queue were treated a bit
differently in the review hook versus the sync hook.
Now they will never qualify for a reward, because only cards in the
review queue should.

Saving configuration on Anki objects

Transition to configuration on the Anki deck object

This update brings many more improvements:

* When cloning deck options, Straight Reward setting will be correctly
cloned along

* Straight Reward settings will be correctly export to .apkg files and reapplied when importing

* Configuration via meta.json is phased out

* Use modern Anki API for saving configurations

* Experimental support for multiple reviews on same card via sync hook

Support filtered decks

Adapt both hooks to work with filters (dynamic decks)

This is not the only feature:

* Fix a bug that would stop the sync hook prematurely
* Rewrite how review hook reversal work: way less error-prone, which is why there is no more notification
* Use Anki exports rather than my own definitions for Revlog types and buttons/answers
