Scala 2.13

[matthewrj]

As of Spark 3.2.0, Scala 2.13 is supported. What would be involved in publishing a 2.13 version of the library? Is there any work underway to support Scala 2.13?

We would likely cross compile and publish artifacts for both scala 2.12 and 2.13. So steps would be:

1. Alter build.sbt to cross compile scala versions
2. Fix any code which breaks from scala 2.13

Is probably not too difficult unless there is a lot of code which needs to be fixed. I don't think anyone has started this unless @kunaldeepsingh has started on it?
