Adapt double flatfield for "Full Radios processing pipeline"

When using FullRadiosPipeline, we load n out of n_angles full radios, where n < n_angles in general for memory reasons.
However, double flatfield (DFF) need to load all the radios.

There are several solutions:

  • Leave the things as they are: an "approximate DFF" is computed by doing the mean over n images (instead of n_angles). It works well on "bamboo" with n = n_angles /2.
  • Perform the DFF step on sinograms. This certainly results in a different DFF.
  • Create a "pre-process" class responsible for doing the DFF from DataUrl, computing the average frame by frame
