   ## What changes were proposed in this PR?
   
   We've spotted several performance hits of map algebra functions:
   
   1. `ImageUtils.createConstantImage` is very slow, we'd better manually 
create a buffered image, which is way faster.
   2. The `.getData()` method on `BufferedImage` objects creates an unnecessary 
copy of the raster object. We've added a utility function to implement a fast 
path for `BufferedImage`.
   
   ## How was this patch tested?
   
   Passing 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.
