Adding in support for the ModalAI IO board. This can be used to interface to PWM ESCs since the VOXL boards have no PWM capability on their own. This code will attempt to detect whether a ModalAI ESC is attached or the ModalAI IO board. Depending on what it detects it will send the appropriate PWM commands.
This has been flight tested with ModalAI ESC to verify that the original functionality has not been impacted.
This has been bench tested with a ModalAI IO board and 4 PWM ESCs. Can arm and spin up motors. RC throttle will control motor spin speed. Still needs an actual flight test but I think the PR is good to go at this time.
