The purpose here is to write a NXtomo file from a set of FITS image files, as fast as possible.

In Mantid we already have the algorithms LoadFITS and SaveNXTomo. These are nice but potentially inefficient when one just wants to generate big NXtomo files as fast as possible.

It may make sense to have this code (something like 'LoadFITSandSaveNXTomoFast') as a Mantid algorithm, and possibly also as a small standalone utility. Workspaces and similar Mantid niceties do not need to be respected/involved here. The point is to load input files and save output files as efficiently as possible.

This requirement became obsolete as support for FITS was added in other tools, and support for NXTomo in third party tools is still very sparse.
It might be resurrected in the future, but it is not in the current "needs to be done" list.
