Manage id15 data

DONE

• try to guess if a dataset comes form 'standard' tomography or XRD-CT
• insure translation for the ID15 use case
• restructure code to get the two cases in parallel. Like create a '_StandardAcquisition' and a '_XRDCTAcquisition' both inheriting from '_Acquisition'
• link this conversion to the existing tomoh52nx
• add 'log' colormap for xrd-ct data interpretation
• diode input should be normalize: diode = diode / mean(diode)
• rework converter to split the Acquisition classes in a different folder
• add documentation
• add unit test for xrd-ct

HOW TO USE

This is directly link to the tomoh5tonx command. And we will add two option to inform about the input format. Because we can try to guess but there is no information about it and e cannot be 100% that our guess will be correct.

• --standard-format: for the 'standard' format. The one we where managing until now (ID19, BM05, ID11...)
• --xrd-ct-format: for the format we will also manage now: ID15...

This is an example of usage:

nxtomomill tomoh52nx /users_ext/datasets/XRD-CT/ID15/glassbeads_Cr2O3_step_scan_20um_res/glassbeads_Cr2O3_step_scan_20um_res_0001/glassbeads_Cr2O3_step_scan_20um_res_0001.h5 output_test.nx --xrd-ct-format
