👌 IMPROVE: Install parallel NetCDF

[chrisjsewell]

This was intended to fix the warning in the output file (installing libpnetcdf-dev):

--- !WARNING
src_file: m_nctk.F90
src_line: 564
message: |
    Netcdf lib does not support MPI-IO and: NetCDF: Parallel operation on file opened for non-parallel access
...

  Asked to delete not existent file: __TMP_FILE__

--- !WARNING
src_file: m_nctk.F90
src_line: 584
message: |
    The netcdf library does not support parallel IO, see message above
    Abinit won't be able to produce files in parallel e.g. when paral_kgb==1 is used.
    Action: install a netcdf4+HDF5 library with MPI-IO support.
...

From https://docs.abinit.org/INSTALL_Ubuntu/:

HDF5, NetCDF and NetCDF-Fortran, libraries to write/read binary files in netcdf4 format. These libraries are available via the libhdf5-dev, libnetcdf-dev and libnetcdff-dev packages from apt. For parallel IO, the libpnetcdf-dev is required.

However, with this addition it is currently still present.
So perhaps it has to be specifically linked to in some way?

@gmatteo do you have an idea what other configuration may need to be specified to get a parallel version of netcdf?
