Codegen in Spark-Alchemy HLL functions

[cozos]

I see that the Spark-Alchemy HLL Functions have the trait CodegenFallback [0]. My understanding is that implementing codegen will give you a big performance boost. Is there a particular reason why Spark-Alchemy does not implement doGenCode, and if not, are there plans to try it in the future?

Thanks

@cozos it's on the roadmap but not a priority at this point. PRs welcome. :)
