profile does not fit into image roi

not runnning

right image orientation when tomo is running

right image orientation when tomo is running

of acquisition in a particular case (pco edge in accumulation with
acc expo time of 10 ms)
Increased time between triggers for pco edge in accumulation
because of instability problems
Added roi spectrums for dark and ref scans to correct projections sinogram

but was disabled on session startup

detector.image.sizes does not exist anymore after bliss merge request !2816

Add possibility to define scintillator associated with the optic and add it
to metadata

Addition of accumulation in default chain

directly attributes from proxy

detector calibration to take into account roi and binning changes

in the measurement group (taken for id11 branch)

Some file cleaning.

Moved as far as possible from proxy access to Bliss parameters.

for ID19 shutters : to not change id19 configs, shutter times are still read
                    from config in milliseconds and converted to seconds
ccd_shutter_time : if not specified in config, set to None. When controlling
                   shutter with CCD, if a fast shutter exist (soft_shutter in
                   config), use its closing time. If not fast shutter configured
                   then use default ccd_shutter_time (in seconds)

- added shutter init() to evaluate shutter type used eventually
  depending on camera config (frame transfer mode on frelon)
- config.get(shutter, None) instead of putting None in config
  which was not properly handled. It is returned as string
  from the config : easier to comment unwanted shutter config line

in TomoCcd: split use_shutter and has_shutter:
- has_shutter defines if the CCD has the shutter capability
- use_shutter defines if the CCD can control the shutter depending
  on its configuration

a string in redis and not as an object anymore

Now it is possible to select one among all detectors already configured.
Modified tomo ccd setup behavior to take into account binning change in
roi setup

Corrected some bugs

              if set to 0, trig difference do not stop scans, used
              for debugging
TomoCcd : init readout_time to 0 to force at least one calibration
          frelon readout_time do not use shutter_time
TomoScan : use shutter_time if shutter_type is CCD in scan point time
           calculation.
           added watchdog_trig_difference member (default to 2) to
           change watchdog behaviour if needed
