Description

presto-orc has very few deprecation warnings and these are probably unavoidable (related to #37)

however presto-parquet has many more. We should resolve them, as they often signal upcoming breaking changes.

Contributor guide

Research direction
Identify deprecated API usages in the presto parquet module and replace them with the recommended replacements. Check the compiler warnings and resolve each.
