Snow pixel masking

[nkhelder]

Hi there, thanks for all your work on this awesome tool. My colleagues and I are hoping to integrate Coastsat into some of our mapping work in Alaska along the arctic coastline, but frequently encounter snow/ice in our imagery that can be problematic. We would love to see some snow pixel masking capabilities (similar to the existing cloud masks) implemented in the processing pipeline, as this would certainly help facilitate our efforts and I imagine other folks using this package in Arctic regions as well.
