Complete the "binary" documentation such that anybody can write a "wrapper"

[DesiOtaku]

Right now, inputmodule-rs is a python + rust project. Great for command line, not so great for developers who wish not to touch either language.

Good news is that there is some binary level documentation available here: https://github.com/FrameworkComputer/inputmodule-rs/blob/main/commands.md

However, it is currently incomplete. Things like how the bytes are oriented for images (left to right then down, or up to down then left to right?), how to make a custom animation, etc. This would be useful for developers who wish to make their own "wrapper" (like a C/C++ wrapper, or somebody wants to write everything in Java) and would not need an external dependency.
