What would you like to see in the tool?

Want to allow parsing of float or any sized integer input DEM. Still expect to use integer values internally, but warn they are being rounded and load file regardless of data type.

Currently, trying to input a raster for dem that uses float gives:

[2026-06-01 09:48:18] FATAL:     Expected integer raster but got SAMPLEFORMAT_IEEEFP
