More VISCA backend commands for PTZOptics cameras

[weekendscribe]

I can confirm that the VISCA backend commands for recalling presets works with the latest PTZOptics Move SE camera.

How difficult will it be to add more VISCA commands to the backend?

I want to send the commands for power ON and power OFF. The codes (and many more) are documented in the camera user manual. https://ptzoptics.imagerelay.com/share/PT-4K-xx-G3-User-Manual

I am on Windows and don't have an environment set up to build my own version.

I'll try to devote some time into looking into this.

Adding new commands is relatively straightforward (backends/visca.h) but requires a rebuild.
