Getting cumulative sums and masks value out of select_ring_peaks_by_intensity

[loichuder]

Again for #358

We would need to get additional data out of the select_ring_peaks_by_intensity function.

Namely, we would need the cumulative sums (defined here:

ImageD11/ImageD11/peakselect.py

Line 89 in d03c18a

cums /= cums[-1]

) and the mask values (defined here:

ImageD11/ImageD11/peakselect.py

Line 89 in d03c18a

cums /= cums[-1]

).

The easiest would be to add additional return values out of select_ring_peaks_by_intensity (and sorted_peak_intensity_mask for the cumsum) but this risks breaking other uses of select_ring_peaks_by_intensity. So we are not actually sure it would be the best solution, what do you think ? Another possibility is to extract common computation in other functions.

Related, we don't need to have plotting since we are only interested in the data. But that is only a minor annoyance since the plot can be disabled by setting doplot to None.

Again, happy to discuss this further with you

I agree - it is very annoying to recompute this all when changing the cutoff parameter. We also need to save cor_intensity (for example, into the colfile, this is needed for plotting and to check the "B" parameter).

Refactoring would be welcome, thanks!
