Improved BOZ analysis

• split BOZ part II into:
  • II.1 processing and saving DSSC data into xarray small data
  • II.2 binning:
    • loading small data
    • binning multiple runs
    • plotting results
    • saving binned dataset
• add to BOZ part I.b extension where validity of correction of previous day can be checked on new data (3 broken membranes)
• DSSC has 'pulseId' overwritten by BAM 'sa3_pId'
• for dark, pedestals is computed as mean, we could compute bounds to find bad pixels as std or percentiles
  • not sure if that is important
• improve finding rois with automatic threshold. In many cases the threshold has to be adjusted
  • not easy to implement
• percentage of shot saturated:
  • give information on the percentage of saturated shots
  • save the percentage of saturated shots in small data attributes
• plot an histogram of Io intensity over run
• save corresponding data of all plots
  • BOZ part I.a
  • BOZ part I.b
  • BOZ part II.1
  • BOZ part II.2

In addition, adds a plot to check the veto pattern.
