Add label with unique detector name on each camera body

• preliminary agreed on unique detector names: 2M.0, 2M.1, 2M.2, ...
• if expected number of detectors more than 10 it is better to use 2M.00, 2M.01, 2M.02, ... (better for files sorting in catalogs).

...

• orientation of all cameras in optical metrology should always be the same
• order of measured points should always be the same

WhyWhy it is important? We have to unambiguously map panels in optical metrology and in data from DAQ. Different detector orientation or different order of measurement need in special treatment in the processing script, which that is error-prone and always needs in verification on real data.

Camera orientation in optical metrology

...

• Engrave detector name on camera body.
• Add labels for unambiguous detector orientation:
  • vector of gravity,
  • x-y (and optional origin) for optical metrology,
  • all labels should be left-to-right readable in the hatch (now for 2M.0 they are upside-down).
• Use the same detector orientation in optical metrology, Q0 is in upper left corner in the hatch and in microscope x-y Cartesian frame. 
  • Origin location does not matter, but it is better to label for uniformity of constants.
• Use the same order of measuring points per quad, as numerated on photo.
• Plug-in properly labeled cables to the properly labeled camera connectors.
