RS_ReprojectMatch

Reproject a raster to match the geo-reference, CRS, and envelope of a reference raster. The output raster always have the same extent and resolution as the reference raster. For pixels not covered by the input raster, nodata value is assigned, or 0 is assigned if the input raster does not have nodata value. The default resampling algorithm is NearestNeighbor. The following resampling algorithms are supported (case-insensitive):

NearestNeighbor
Bilinear
Bicubic

This function serves the same purpose as the RasterArray.reproject_match function in rioxarray.
