mwocp68: add commands for firmware update (#16)

This adds some additional PMBus support for the MWOCP68-3600 series,
specifically around the commands necessary to support firmware update.
(This also performs some minor cleanup, bumping the Rust version
to 1.84 and fixing the resulting clippy warnings.)

 pmbus: A crate for PMBus manipulation
 
 This is a no_std crate that expresses the PMBus protocol, as described in
-the PMBus 1.3 specifcation.  This crate is intended to be generic with

 respect to implementation and usable by software that will directly
 communicate with PMBus devices via SMBus/I2C as well as by software that
 merely wishes to make sense of the PMBus protocol (e.g., debuggers or
