Adds a new build option, -DVIDEO_PIN=<n>, which sets the base GPIO of Video (followed by syncs). The video pins (for PIO reasons) need to be contiguous, numbered upward from the DATA pin. This has caught a couple of people out, so to make it easier just define them this way. That then gives a single configuration option, the first GPIO, setting it all up.
