Expand ASIAIR Focus feature to facilitate switching cameras

Foobaria

Under focus feature, make it easier to switch to the next camera, as the focus feature is need for both the main and guide camera, and an easy way to switch to the next camera, or between guide/main would help. As it is, you have to unload the camera from main, and select the guide camera as if its the main camera to focus it, and then put it back, which is pretty tedious.

Tech@ZWO But we still need to focus the guide camera using the FOCUS feature using manual methods, so FOCUS is still needed for Guide Camera as well as EAF. It is needed for EAF when first started to get the main camera to get the scope into close focus before doing EAF. I have not tried this in Guide interface, I will try this.
