midi_driver_get_event_size: This is a convenience function for finding out the size of the event based on the status byte.

: Status (first) byte of the event.

Returns: Size of the event (in bytes). If 'status' argument is invalid (< 0x80) or 'status' represents start of the "SysEx" event (0xF0) this function will return 0.
