octopus-foundation/gremlin.zig: A zero-dependency Google Protocol Buffers implementation in pure Zig. Single allocation encode and lazy decode

Gremlin is a zero-dependency implementation of Google Protocol Buffers in pure Zig, requiring no additional tools like protoc. It supports Protocol Buffers version 2 and 3, integrates easily with Zig's build system, and features single allocation for serialization and lazy parsing. The process involves adding the dependency to your `build.zig` file and specifying the input and output directories for .proto files.
