Updates mesh reader for shear waves

- Implements point::properties for shear waves.
	- To do this I create a base class with medium_tag = specfem::element::medium_tag::elastic
- Implements medium::properties for shear waves
	- Again this is implemented with a base class with medium_tag = specfem::element::medium_tag::elastic
- Update specfem::IO::read_mesh signature to include a elastic_wave argument. The elastic_wave would be set up using specfem_config.yaml
- Updates tests for the mesher
