Molfile plugins not compiled in

[awacha]

• [X ] I read the conda-forge documentation and could not find the solution for my problem there.

Issue: .gro files are not supported, probably because the molfile plugins are not compiled in, as they need libnetcdf. A "{{ pin_compatible('libnetcdf', max_pin='x.x') }}" in the dependencies should do the trick (I do the same in my pymol-open-source build in the "awacha" anaconda channel). The pinning is needed because the so version changed recently.
