Patch Changes

• aa48e04: feat: add a snapshot-end control message to the end of snapshots

• 965ef47: feat: add support for changes_only mode, subset snapshots, and offset=now

  • changes_only - in this mode the server will not create initial snapshot for the shape, the clients will start receiving changes without seeing base data. Best paired with...
  • Subset snapshots - the server now accepts a subset__* set of parameters, which when provided result in a special-form response containing a snapshot of a subset (may be full) of a shape, and information on how to position this response in the stream. The client exposes a new method requestSnapshot which will make this request and then inject the response into the correct place in the subscribed messages stream, bounded with a snapshot-end control message.
  • offset=now - the server now accepts a offset=now special value, in which case the client will receive an immediate up-to-date response with the latest possible continuation offset, allowing it to skip all historical data and start "from scratch". This works best with changes_only and subset snapshots where a client doesn't keep state and upon a reload needs to start fresh without historical data.
