Allow for a dynamic number of OptoHybrids

Laurent Petre requested to merge feature/dynamic-number-oh into main


Title says it all: this MR aims at retrieving the number of OptoHybrids from the firmware registers, avoiding to edit the cmsgemos code to run with some firmware flavors.

No behavioral change is expected. Performance impact is minimized by caching the value on the first successful register access.
