incorrect reporting of beam stop for high resolution detector

When the converging beams are used (and probably other conditions) the beam stop diameter is reported for the high resolution detector as "NaN". This results in the resolution function (all three columns) returning NaN. The data is still averaged correctly, but any analysis is not possible since the NaN is forces the data to be interpreted as slit-smeared data when loaded.

Patch utility will need to be updated in the short term to correct the metadata
Long term solution involves correcting the values in NICE.

Currently (10/2019) I do not know what the actual beam stops are for the high res detector, and how to identify them correctly in the averaging logic (for resolution).
