Writing grid obtained via localgrid to file

[erny123]

Looking to see how I could save other types from the PencilArrays package.

for example:

using MPI
using PencilArrays
using HDF5

MPI.Init()
comm = MPI.COMM_WORLD


Nx, Ny, Nz = 65, 17, 21
xs = range(0, 1; length = Nx)
ys = range(-1, 1; length = Ny)
zs = range(0, 2; length = Nz)

pen = Pencil((Nx, Ny, Nz), comm)


grid = localgrid(pen, (xs, ys, zs))


fid = open(PHDF5Driver(),"test.hdf5", comm; write=true);

fid["grid"] = grid 

This obviously doesn't work. The following error is from my own code but should be similar:

The PHDF5Driver (and the MPIIODriver for that matter) does not currently support writing grid objects returned by localgrid. This is definitely something which would be interesting to have.
