When codegen support was added to enable protocol buffer schemas, oneof fields were left out and handled via map lookups. This was because ByteBuddy does not provide an easy way to generate conditional code.
In this PR we use the underlying ASM framework to generate switch/case statements to handle oneofs, and remove the slower map-based code path.
