[Feature Request] Option to provide scrip file for exact grid cell visualization

[whannah1]

Paul clarified how ncvis does the resampling, which is good to know, but in some edge cases when dealing with noise at the scale of the grid it would be nice to be able to provide a scrip file to visualize the exact cell outlines and not worry about any visual distortion from the resampling.

Given how ncvis is supposed to be a simple quick viewer, I think exact cell visualization might be out of scope.
