Int32 cells interpreted as float32 cells

Describe the bug

When trying to read geotiffs saved as Uint32 using GdalRasterSource, the tile is interpreted as float32 and all data come back as no data.

To Reproduce

Provide as able:

• Steps to reproduce the behavior
  Open UInt32 raster using GDALRasterSource and read pixel valiue

• Inputs

Presigned link to input file (expires April 15, happy to update link if required).
This file is saved using datatype=UInt32 and nbits=17

Same file but using datatype=UInt32 and nbits=32 (same result)

• Actual output
  Float32 tile, all pixel values are no-data (see screenshot)

• Expected output

Uint32 tile with correct pixel values

Expected behavior

Return Uint32 tile with correct pixel values

Environment

• Scala version: 1.12
• GeoTrellis version: 3.5.1
• GDAL 3.1.2

Start at the GdalRasterSource entry point and reproduce the issue with the provided UInt32 GeoTIFF inputs. Trace how the raster datatype becomes Float32, then verify completion when reading the files returns a UInt32 tile with the correct pixel values rather than no-data values.
