Refactor typings + extra configs forwarding

[fmigneault]

• relies on provide DGGRIDv8 and support its hierarchy indexing system #26 (mostly for the extra indexings added with v7/v8 distinct classes)
• Adds python typings for all parameters of DGGRID and functions/methods of dggrid4py
• Reuse and extend the specify_resolution, specify_topo_aperture and specify_orient_type_args functions that were available inside the respective DGGRID calls to allow overriding with custom attributes
• Simplify the Dggs class by leveraging dataclasses

@allixender @tik65536 Let me know what you think of the proposed changes.

I think they should help us with latest alignment with DGGRID and customizing the results.
Notably, it should be easier to configure the vect0 parameters to configure what is needed for LandscapeGeoinformatics/pydggsapi#11

Let's give it a shot :-)
