Description
Not sure if an issue or incompatibility. Using the updated release (0.10.31-rc.1), the importer will import TIF formatted rasters as "ZLIB Deflate (26)", which subsequently cannot be read by HMS 4.8. Reverting back to the older release (0.10.27-rc.2), the first raster imported would be imported as "ZLIB Deflate (26)", but subsequent rasters would import as PRECIP_2_BYTE, which can be read by HMS 4.8.
Is there somewhere to specify the compression method to ensure all rasters are imported as PRECIP_2_BYTE? Note, all input rasters are 32BIT Float raster (MRMS/StageIV/AORC), with the naming convention of: precip_XXX_to_XXX.tif, and are recognized in HEC DSSVue as precip data.

Research direction
Start by reproducing the import with the listed Vortex releases and 32-bit Float TIF rasters, then inspect the importer path that writes HEC-DSS compression metadata. Compare the resulting compression methods in HEC DSSVue and HMS 4.8. Done means all applicable rasters import as PRECIP_2_BYTE and remain readable by HMS 4.8, or the incompatibility is documented.
