This PR drops our dependency on parquet-cascading for easier cascading upgrades in the future (decoupled from apache's parquet release process).
As a follow-up to this change, I will copy over @cchepelov's cascading3 changes from apache/parquet-java#284 and file an issue on parquet-mr to possibly remove their version of this code (presumably, no one outside of scalding consumes this).
