Aimfast and cataloging updates

[Athanaseus]

• [x] Enable online catalog comparison (nvss, sumss,) and plot comparisons of consecutive self-cal steps
• [x] Convergence criteria are now optional

aimfast:
  enable: true
  plot: true
  convergence_criteria: ''
  online_catalog:
     enable: true
     catalog_type: nvss

If aimfast is enabled, the following json file will be generated containing stats for each selfcal iteration.

$ cat fidelity_results.json
$ {"cube.residual.fits": {"SKEW": 0.124, "KURT": 3.825, "STDDev": 5.5e-05,
                          "MEAN": 4.747e-07, "MAD": 5e-05, "RMS": 5.5e-05},
       "cube.image.fits": {"DR": 35.39, "deepest_negative": 10.48,
                           "local_rms": 30.09, "global_rms": 35.39}}

If aimfast:plot:true the following plots are generated for each iteration. FluxOffset.html PositionOffset.html SourceResidualNoiseRatio.html & RandomResidualNoiseRatio.html

If aimfast:online_compare:true It will generate OnlineFluxOffset.html & OnlinePositionOffset.html In case no matches are found online (i.e. nvss/sumss) a friendly warning is logged.

• [x] Source find on breizorro generated image that mask out extended emission, this is the catalog to be used for cross-matching purposes.

  extract_sources:
  enable: true
  breizorro_image:
  enable: true
  sum_to_peak: 100  # Sum to peak ratio of flux islands to mask in the original image.
                     Default = 100, will mask everything with a ratio above 100.

Original MFS image compared to generated breizorro image.
