[Nexus] nexus units

[Paul Kienzle]

Hi,

When trying to decide what units to use for monitor rate, I wanted to know what was already in use in the NeXus world.

I wrote a little script (see attached) to walk the github nexusformat/exampledata repo and list all the units used in the files.

The results are shown below.   

Many thanks to those facililities that have supplied data files (Soleil, APS, IPNS, ANSTO and SINQ).  I’ll include some NCNR files once we have settled on the format.

I updated units.py to accept all these units.  This should be able to replace the version in bindings/python/nxs.
