Support live adjust of certain camera parameters

[nclack]

To support lightsheet, it's helpful to control exposure time and slit width live.

For the orca fusion this is

• acquire-project/cpx#42
• acquire-project/cpx#43
• acquire-project/cpx#44
• add camera prop global vs rolling shutter

Currently parameter set/get stops the camera (at least for dcam). So another task is to:

• support live adjust of some params on dcam acquire-driver-hdcam#43

Rolling shutter w lightsheet does exposure reset just before a line is exposed again. Setting lightsheet mode might imply rolling shutter.

When lightsheet is enabled. HCImage enables the following advanced props:

• READOUT_DIRECTION
• TRIGGER_GLOBAL_EXPOSURE

TIMING_EXPOSURE is not enabled - constitutively set to ROLLING.

May need to set some "Speed" parameter to "Fast" as opposed to quiet or standard.
