Describe the bug
DEMs created with for instance ArcPro have a fill value set to 1e+38. This value is not picked up by ncread and then can negatively impact interpolation of topobathymetry to the mesh vertices.

Proposed fix
Put in a logic in GridData to catch abs(bathymetry) values larger than Mariana's trench and set them to NaN.
