Network without face coordinates cannot be added to mdu

[veenstrajelmer]

Describe the bug
Network without face coordinates cannot be added to mdu. It is a valid network (and it is how the interacter writes them). However, adding them to the mdu raises: "KeyError: 'An attribute for "mesh2d_face_x" was not found in nc file. Expected "mesh2d_face_x"'"

To Reproduce

import hydrolib.core.dflowfm as hcdfm
mdu = hcdfm.FMModel()
netfile = 'network_nofacecoords_net.nc'
mdu.geometry.netfile = netfile

Expected behavior
If the network validation is not proper, it is better to do no network validation at al (at least temporarily). I think the mesh2d variable is not being read also and the variables are hardcoded.

Version info (please complete the following information):

• OS: Windows
• Version: hydrolib-core main branch

Additional context
The network:
network_nofacecoords_net.nc.txt
