Weird Crashes when running `Shipwreck Seeker` twice

[schefferac2020]

Crashes when run on the same raster. Partially related to temp_chunks not being properly cleaned up

Seems to be a memory issue. Not closing datasets?

Largely is just opening rasters directly into memory that are too large

For now, the temporary solution is simply to recrop the input rasters to smaller sizes by going to Raster->Extraction->Clip Raster By Extent
