React hooks for sync streams

[simolus3]

This updates the react package to expose hooks for sync streams:

• The useSyncStream() hook has been added. It takes name and parameters of the stream, along with optional subscription options. When called, it:
  • creates a stream subscription on the requested stream
  • returns the current subscription state of that stream subscription
  • unsubscribes when the component is unmounted
• The useQuery() hook has been updated to optionally take an array of streams as well.
  • Similarly to useSyncStream(), it subscribes to those streams while the component is active.
  • Additionally, it delays the queries until the subscriptions have been synced at least once. This is a neat shortcut to display a loading state while data is downloading / querying from the database and then transition to data once it's available.

I've also fixed a few minor issues with the sync stream implementation in this PR.
