Joe Tsai fc5f8c340a encoding: optimize for oneofs

Suppose a oneof has N fields, the previous marshaling logic
would traverse every field checking for presence. This is O(N).
Using the protoreflect.Message.WhichOneof method, we can reduce
this to O(1). This optimization is exceptionally useful for oneofs
with a large number of fields.

Next Generation Go Protocol Buffers

WARNING: This repository is in active development. There are no guarantees about API stability. Breaking changes will occur until a stable release is made and announced.

This repository is for the development of the next major Go implementation of protocol buffers. This library makes breaking API changes relative to the existing Go protobuf library. Of particular note, this API aims to make protobuf reflection a first-class feature of the API and implements the protobuf ecosystem in terms of reflection.
