1675 read cosserat mesh

[maxlchien]

Description

Adds a branch to read in elastic cosserat materials from the mesh file.
They are specified with material_id=4. For instance, the following line in a Mesh_Par_file:
1 2300.0 1500.0 2800.0 1e6 1e4 300.0 25.0 500.0 4
produces a material with
$\rho=2300,\kappa=1500,\mu=2800,\nu=1e6,j=1e4,\lambda_c=300,$ (4 specifies cosserat materials), $\mu_c=25,\nu_c=500$

An additional test case for mesh reading for Cosserat materials is added under tests/unit-tests/data/dim3/EightNodeElasticCosserat/.

Issue Number

devel has now been merged, fixing the previously failing tests. There will still be failing tests for the new EightNodeElasticCosserat case until #1739 is merged.

Hi @maxlchien, I created a temporary branch so that the tests can also be updated before we merge into devel. Can you change the base for #1739 to 1675-cosserat-mesh
