Consider interpreting naming conventions from the Nexus format

[SimonHeybrock]

See https://manual.nexusformat.org/datarules.html?highlight=uncertainties#rules-for-storing-data-items-in-nexus-files, specifically the "Reserved suffixes", e.g., _mask is something we could handle:

Reserved suffixes

When naming a field, NeXus has reserved certain suffixes to the names so that a specific meaning may be attached. Consider a field named DATASET, the following table lists the suffixes reserved by NeXus.

suffix	reference	meaning
_end	NXtransformations	end points of the motions that start with DATASET
_errors	NXdata	uncertainties (a.k.a., errors)
_increment_set	NXtransformations	intended average range through which the corresponding axis moves during the exposure of a frame
_indices	NXdata	Integer array that defines the indices of the signal field which need to be used in the DATASET in order to reference the corresponding axis value
_mask		Field containing a signal mask, where 0 means the pixel is not masked. If required, bit masks are defined in NXdetector pixel_mask.
_set	target values	Target value of DATASET
_weights		divide DATASET by these weights [4]
