SDK cameras no longer working

Describe the bug
Changes to the camera base class have stopped the SDK cameras (ZWO, FLI, SBIG) from working.

To Reproduce
Steps to reproduce the behavior:

  1. Attempt an instance of an SDK Camera class
  2. See errors due to attempts to assign to read-only is_exposing property

Expected behavior
SDK camera instances can be created and used.

Additional context
The root cause of this problem is changes to the camera base class (and DSLR camera class, and camera simulator) to use the is_exposing property as an alias for _is_exposing_event,is_set(), and, more specifically, using assignment to is_exposing to set/clear this event. For the DSLRs this property is read only, and directly tracks the internal state of the camera hardware.
