proto: add tests for unmarshalling invalid field numbers

This change adds tests for unmarshalling fields with various invalid field
numbers. Our current behavior is that proto.Unmarshal will return an error when
it sees zero and larger than max field numbers and return nil for reserved
ones, which matches the C++ behavior. (Note: depending on which parser helper
in the C++ implementation, one may need to call additional method to check the
result, which we don't have in Go)

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.
