Conda versions of parallelio being built without PNetcdf support

[nickheavens-cgg]

After a long struggle to figure out why I couldn't get MPAS-A to run with the default PNetcdf I/O but successfully with Netcdf-3 serial I/O, I have determined that the ultimate issue is that the conda version of parallelio I am using was built without PNetcdf support, as below. 2.5.10 is similar. I cannot figure out who is uploading this package; it's coming out of a general Conda pipeline account, but I would humbly request that they would build ParallelIO with such functionality, so that it doesn't break the default input/output mechanism in MPAS.

I have opened an issue on the conda-forge page. conda-forge/parallelio-feedstock#14
Note that parallelio is also in spack and can be built with pnetcdf support there.
