Hi, I stumbled across the fact that the monitor can list all registers via mon lr, but can only read from at most a peripheral (e.g. mon rr tca0)

I use bloom remotely over a local network connection and the network overhead is massive when using 20x mon rr compared to a single mon lr. So if nothing else there would at least be me who would be quite happy about seeing an option implemented with which to read all register values :D

I am considering adding this feature myself via a PR, but before trying it out I'd like to ask whether this has already been considered and there was a technical reason not to do it.
