Intent

Create overview cameras from the two microscopes that can be seen when the control drawer is open. This will help ease alignment of each sample. The plots are now contained in cells so only a subset are seen when the drawer is closed (to maximise the visualisations when on second screens in ViSR.

Changes

• move CamPva to its own file
• use disconnected symbol if we cannot receive frames
• add visr's two usb cameras to the gui, one for spectroscopy and one for tomography, to view the stages/samples live
• only show these when controls drawer is expanded
• add composite plot placeholder to spectroscopy

Closes issue #246

Spectroscopy

Tomography

Looks good to me!

Technically, there is coverage regression as more code has been added without tests, but given the lack of tests generally in the visr app, this is not a problem unique to these additions.

Merged in changes from enz locum PR

Updated so that composite image follows the style of other plots without data (diagonal lines)

Yes i agree - in general i did not add tests to the visr app as there weren't any there to begin with, I will make an issue to start making tests once we are happy with these recent changes.
