Remove dependency on DeltaShell-modified netCDF files

[kdberends]

Currently we need modified netCDF files (using the _sectionbathy and _regionbathy convention). This is undesirable, as it requires the user to be familiar with DeltaShell and DeltaShell coding, and because it adds a dependency on python support in DeltaShell.

Alternatively, see if an external module (e.g. meshkernel) could be incorporated.

31/7/2023 meeting with dev MeshKernel:

• MeshKernel has python wrappers for functions like 'inpolygon'.
• Reading/writing netCDF is not done by MeshKernel. Need to implement own functionality.
• Alternative option is to use Hydrolib-core, which may have all functionality we need to read & write grid files and uses MeshKernel for grid operations.
• May need to introducte 1 (hydrolib-core) or 2 (hydrolib-core + meshkernel) additional dependencies.
  • MeshKernel API is relatively stable
  • Hydrolib-core API is at version 0.5.

Actions:

• Refine this issue
• Implementation end of year
