reflect/protoreflect: clarify Range semantics

Restrict mutation operations during Range to only the current iteration key.
This simplifies the guarantees that any given implementation may need to provide.

While none of the range operations have a defined order, UnknownFields.Range
is special in that the iteration order is at least deterministic.
This exception occurs because there is no obviously correct way to re-order them
(since order of unknown fields can have semantic significance).

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.
