Separate domain into high resolution and working resolution grids #5

Conceptually, it would be great to improve the model such that the standard domain grid, from which boundary information like bedrock topopraphy in particular is obtained, could be a different (higher) resolution grid than the computational grid of the ice sheet model itself. This has the advantage of providing a lot of subgrid information to the ice-sheet model, such as bed roughness on the computational grid cell, sub-grid pinning points, grounded fraction etc. Thus even for low-resolution ice-sheet simulations, significant information about the domain in reality would be retained.

To do this would likely require some major changes to the yelmo derived type (at a minimum another sub-type), and possibly breaking changes to the API.
