Add RS_MakeRaster for constructing a new raster using given array data as band data

RS_MakeRaster takes 2 arguments:
1: The reference raster. The created raster should have the same width, height, geo-reference metadata, and CRS as the reference raster.
2: The array data. The length of the array data should be multiple of width * height.

This function is useful in various scenarios, such as converting a mask for a given raster to a raster object.
