This is somewhat related to the awesome work by @Kontinuation in https://issues.apache.org/jira/browse/SEDONA-207
Although this patch only changes the Spark type once serialized and SEDONA-207 addresses the actual serialization.

@Kontinuation if you are already doing these changes in your work we can hold this PR
