feat (lsz_ptz_camera): add compatible Merkury CW035 camera
- additional dps not added, as they are not supported by other compatible devices
- this model does not present many dps for matching, so only supported by product_key match.
Extra unsupported dps:
- 101: indicator light
- 212: general push message
- 239: motion detection event
The first two are fairly standard on other cameras, but since they are
unsupported by the LSC, and other compatible cameras up until now, and because
the dps detection of these cameras doesn't really allow hiding undetected dps
they are left out for now.
