Single Stepping Mode #6

Silly thought about this eventual feature: would it be possible/preferable to actually just send the start/stop/step sizes to the Pico and have it actually program the individual single tone steps instead?

I ask because the novatech has pretty slow serial comms, and programming a dense sweep can take many seconds. If it were faster to send the relevant info then have the Pico internally generate the table (rather than the user pre-generating it and sending it over serial), that may actually be a good value add for this bit of functionality. It does rely on the Pico having fairly fast computations/memory management for doing the math on board though.
