General Purpose I/O Plugin

This plugin controls the General Purpose Digital I/O (GPIO) pins on devices
like a Raspberry Pi. It creates a single device, with a single output port.
The offset (start address) of the GPIO pins is configurable.

Config file: ola-gpio.conf

gpio_pins = [int]
The list of GPIO pins to control, each pin is mapped to a DMX512 slot.

gpio_slot_offset = <int>
The DMX512 slot for the first pin. Slots are indexed from 1.

gpio_turn_on = <int>
The DMX512 value above which a GPIO pin will be turned on.

gpio_turn_off = <int>
The DMX512 value below which a GPIO pin will be turned off.
