support reproject to bounds edge

filter out infinity values

[DanielJDufour]

what if a bounding box has infinity values along every edge?
one solution could be to treat the bbox as a grid, drop points evenly spaced throughout the inside of the bbox, reproject every point, and then recalculate the bbox

that would be a fairly simple solution and without regression from the current point density approach. the current point density approach drops points evenly along the edges. this would just add points to the interior as well

not perfect, but if you reproject with nan_strategy = "skip" AND high density, you'll get close to what you want.
