The majority of the write checkpoint operations are specific to a specific set of sync rules (takes With that done, we could calculate the write checkpoint mode once when MongoSyncBucketStorage is instantiated, and don't need to watch for any changes. |

This has the potential to add a lot of overhead - the rest of the change stream is optimized to get checkpoint updates with as little latency as feasible. It also shouldn't be needed - the content of a sync rules document never change.
That does seem better. I've implemented that here. I'll close this PR since it will no longer be required. |

Overview
This builds on-top of #105.
This adds the ability to set the storage's Write Checkpoint mode after the storage's initialisation.
Setting the Write Checkpoint mode often depends on the active Sync rules. This adds a
watchActiveCheckpointmethod on theBucketStoragewhich should yield the active checkpoint and active Sync Rules.This also adds plan parameters to the PowerSync config file.
