[Feature request]: Improve support for SoloCam E30 (T8171)

Describe the solution you'd like

Hello, I have managed to get my Solocam E30 (T8171) working, but I cannot get the PTZ controls to function and cannot control the preset zones and other features. Is there an update planned to make them work? I am available to perform some tests.

It seems that the controls were not included at first, for pan/tilt, calibrate and zones
