NexusWriter. Add NXroot@file_name and (less important) NXroot@file_time
NexusWriter and LImA have to add the full path and creation date to the generated HDF5 files in @file_name and @file_time. Beamlines requesting it are implicitly assuming that information about proposal and dataset will be contained in the file full path therefore allowing traceability if the file moves. That is particularly true for LImA that uses generic file names.
file_time is less critical because we have the time of the first scan, but it is convenient.
