🎁 Features

Expand kvStore constructor parameter. Before the kvStore only allowed customizing how to create key-value stores, now it allows customizing deleting them too. The kvStore option has been expanded into a KVStoreProvider which has both the create and delete function.
Remove the experimental tag from kvStore.
As a convenience you can specify kvStore: 'mem' and get a memory implementation rather than having to implement KVStoreProvider manually.

Treat all non-200 responses from push or pull as an error
Starting in Replicache 13, cookies uniquely identify server states. Duplicate cookies are supposed to be assumed to mean that nothing changed, and be ignored. However, we weren’t consistently doing this:
- The cross-tab sync wasn’t consistently doing this, meaning you could temporarily see a pull response with a duplicate cookie honored, but then reverted.
- We were in some cases honoring pull responses with duplicate cookie if the lastMutationIDChanges was non-empty.
Allow explicit undefined for prefix and initialValuesInDiff params to watch.
Ensure return is called in mergeAsyncIterables on passed in async iterables. mergeAsyncIterables is a utility function that is provided to make implementing scan for your custom JS backend easier. It is common to have Iterables and AsyncIterables have a return method. This return method allows cleaning up resources when the iteration is done.
Include detailed error messages when cookies don’t increase monotonically, or if something changes in the pull response but the cookies doesn’t increase as it should.
Ensure the limit parameter is enforced when an index is passed while performing a scan.

The change to kvStore above is a breaking change, albeit to an interface that was previously marked experimental.
The change to how cookies are treated is breaking. If you were changing last mutation IDs without updating the cookie these changes will no longer be honored (at least until the next change to the cookie).
