Problems with udunits in CDAT82

[durack1]

I have just encountered the following issue while trying to load vcs

import vcs
~anaconda3/envs/cdat82MesaPy3/lib/python3.7/site-packages/unidata/__init__.py:2: UserWarning: unidata package is deprecated please use genutil.udunits instead of unidata.udunits
  warnings.warn("unidata package is deprecated please use genutil.udunits instead of unidata.udunits")

Might be something quick to fix before 8.2 is officially released

@durack1 thanks for the report, looks like @muryanto1 has fixed this CDAT/vcsaddons#45. Will be in the CDAT 8.2.1 release.

@jasonb5 perfect, looking forward to seeing this land!
