Reconciling changes to main PWA repo

[ThomasSaleh]

The original code in the main PWA repo was retained at the time where this HC tool was created. Changes have since been made which may need to be incorporated to the present repo for consistency.

Bug fixes (transfer to hc module):

• Raster resample relies on gdal rather than wbt (potential bug fix. Check final HC functionality after new features are added and migrate if necessary)

New features (check for equivalent functions in hc module and migrate if necessary):

• New feature to handle multiple lidar rasters
• CRS in inputs and outputs is not actively managed
• WBT zonal statistics doesn't seem to be accounting for pixel size, so the outputs need to be adjusted for pixel area. Previous code had a hard-coded multiplier 55
• New feature to align the depression raster with the hydrofabric raster

After these fixes, the module should be tested using a test script in the PWA-hydro-conditioning-main repo.

Bug fixes (transfer to hc module):

Raster resample relies on gdal rather than wbt (potential bug fix. Check final HC functionality after new features are added and migrate if necessary): the hc module also uses gdal, rather than wbt, to resample rasters, so it's up-to-date for this feature, and there's no need to transfer this to the hc module.

New features (check for equivalent functions in hc module and migrate if necessary):

• New feature to handle multiple lidar rasters: this does not need to be migrated to the hc module; the hc module already has a feature to handle multiple lidar rasters.
• CRS in inputs and outputs is not actively managed: If you mean that the hc tool doesn’t check whether datasets have the same CRS before working with them, I’m fairly certain it does. The hc module ensures CRS consistency before every operation, such as stitching or clipping.
• WBT zonal statistics doesn't seem to be accounting for pixel size, so the outputs need to be adjusted for pixel area. Previous code had a hard-coded multiplier 55: yes, this indeed needs to be done.
• New feature to align the depression raster with the hydrofabric raster: Are you referring to the wetlands raster when you say the hydrofabric raster? In that case, the hc module generates the hydrofabric raster with the depression raster, so they should be aligned by default. But maybe I'm misunderstanding?
