https://issues.apache.org/jira/browse/SEDONA-366. The PR name follows the 
format `[SEDONA-XXX] my subject`.
   
   ## What changes were proposed in this PR?
   
   The current implementation of `RS_Count` calls `GridCoverage2D.evaluate` for 
each pixel, which calls `getTile` method for each pixel. This is very slow for 
some implementations of RenderedImage. In this patch, we get the raster of the 
image and iterate through the samples, which is much faster.
   
   ## How was this patch tested?
   
   Passes existing tests.
   
   ## Did this PR include necessary documentation updates?
   
   - No, this PR does not affect any public API so no need to change the docs.
