We added additional AbsoluteMove PTZ example. Works confirmed on HikVision PTZ (HIKVISION DS-2DE2204IW-DE3 2MP IP PTZ )

I have a IMOU Ranger 2C 4MP model. I try to run the AbsoluteMove example provided in this PR, but I gon the following error:

During handling of the above exception, another exception occurred:

What does this mean? Possibly my camera does not implement the AbsoluteMove action and so the only option I have to move it is thought the ContinousMove request?

I can verify that it is able to move a Bolin EXU248FW Outdoor 4k PTZ . There is one problem, which I think is the camera's fault. ptz.GetStatus({'ProfileToken': media_profile.token}) always returns PanTilt coordinates of zero.
