One ROM Protocol
A crate defining the protocol used to control One ROM Lab via SWD, carried over
airfrog-rpc.
Deprecated. This protocol served the original STM32F4-based One ROM Lab. The current One ROM Lab is Fire (RP2350) firmware driven interactively over USB CDC, and does not use this crate. It is kept in the tree because the approach may return, so do not build anything new on it.
