What raster tools are you missing?

[brendancol]

If there's a raster operation you keep writing by hand or pulling from another library because xarray-spatial doesn't have it yet, tell us here.

When suggesting something, it helps to mention:

• What does it do? (a sentence or two is fine)
• Where have you seen it? (GDAL, ArcGIS, QGIS, WhiteboxTools, a textbook, etc.)
• How often do you actually need it?

Don't worry about whether it "belongs" here. If you've wanted it, mention it.
