Google Protocol Buffers Tools

`pbtools` is a Python library for working with Google Protocol Buffers. It provides tools to read, write, encode, and decode Protocol Buffers messages (both binary and text) directly from `.proto` definitions, *without* requiring generated Python code. This simplifies field access and enables decoding of unknown messages. The current version is 0.47.0, and it maintains an active release cadence with incremental updates.
