Reading meshes from StringIO or BytesIO objects

[gatling-nrl]

I've got the text data of a gmsh mesh in memory and want to feed it to meshio using either StringIO or BytesIO instead of writing it out to a file and passing the file name. This fails and I've traced the problem down to this line:

meshio/src/meshio/gmsh/_gmsh41.py

Line 122 in 0138cc8

fromfile = partial(np.fromfile, sep=" " if is_ascii else "")

And this open (and ancient) issue in numpy.

This sits somewhere in the grey space between bug and feature request. Is there any workaround in meshio? There is a workaround suggested in the numpy issue comments, but requires changing meshio.

Hi @gatling-nrl ,

I have an opened PR for this issue: #1305
Does it work for you?
