This commit introduces a couple of new units of measure for
ICD-related quantities, especially AICD and SICD strength
parameters. Add base unit "GeomVolume" ([Length]**3) and 'measure'
entities
geometric_volume (= GeomVolume)
geometric_volume_rate (= GeomVolume / Time)
icd_strength (= Pressure / (GeomVolume / Time)**2)
Add conversion factor unit tests for these, and also complete the
set of unit tests for FIELD, LAB, and PVT_M to cover measures that
were not already there.
Also add a parser Dimension ("GeometricVolume") to play the role of
[Length]**3 in .json files.
