We probably should issue a warning about excessive memory usage when using Cholmod with large grids. Perhaps over 5M cells?

#232 (comment)

A warning that may be clear is something like "Cholmod is a spare direct solver that consumes a lot of memory. A landscaspe with 5M cells will require roughly XGB of RAM. Please use cg+amg`.

Also, when the grids are large enough, we should either automatically use 64-bit indexing, or issue a warning.
