Description of Change

The subdriver existed to handle devices that send position updates while the shade is in motion. This PR integrates the functionality from the subdriver into the main driver in order to avoid having to maintain a subdriver.

Summary of Completed Tests

Needs testing on devices that send position updates while in motion as well as devices that do not.
