HydroMT: have both 1D and 2D in mesh component

[hboisgon]

So far, we use self.mesh for the 2D mesh and self.branches for 1D (GeoDataFrame) and self.dfmmodel.netfile.network._mesh1d. Ideally all mesh components should be contained into self.mesh and we should use xugrid / meshkernel functions for every mesh manipulations without having to use hydrolib-core classes in between.

This requires the following changes:

• adapt setup_mesh
• adapt write_mesh
• self.mesh1d should be derived from self.mesh usig xugrid
• adapt self.set_mesh1d: this requires rewritting mesh1d_add_branch to avoid using hydrolib-core class and meshkernel/xugrid functions directly and updating self.mesh instead of self.dfmmodel
• self.network1d_nodes
• self.mesh2d
• self.set_mesh2d
• self.branches to be derived from self.mesh with xugrid

update: xugrid now supports mesh1d
