Is this PR related to a JIRA ticket?
[SEDONA-XXX] my subject.What changes were proposed in this PR?
Currently, GridCoverage2D objects are serialized using Java serializer, which is painfully slow. It proved to be a bottleneck of various raster processing jobs.
We found that the serialization of CRS objects is a performance hit. We found that the number of distinct CRS objects won't be large throughout the entire raster dataset, so we cache the compressed serialized CRS objects and reuse them.
How was this patch tested?
Passing existing tests. We've also added several new tests and refactored some existing tests.
