proto.zig
I really needed proto2 support in zig, so I made a package supporting that.
This even has support for the archaic groups feature.
This was mainly an excuse to try out the new io interface 
.
I tried to keep it lean when it comes to codegen. No functions are generated in the types, like it would in zig-protobuf.
Only encode & decode support has been implemented, no json or streaming support.
Supported Zig versions
Only supporting 0.16.0 as of now.
AI / LLM usage disclosure
I used AI to diagnose errors during testing. The code is not AI generated.
