support for RPI Sense HAT

[DewitteRuben]

sense = SenseHat()
File "usr/lib/python3/dist-packages/sense_hat/sense_hat.py", line 39, in init
raise OSError ('Cannot detect %s device' % self.SENSE_HAT_FB_NAME)
OSError: Cannot detect RPi-Sense FB device

According to the minimal research I did, it seems like I2C needs to be enabled. In the boot config we already do dtparam=i2c_arm=on but i'm not sure if that suffices.

What may also be required is the following dev rule for the GPIO pins (not sure)

Create /etc/udev/rules.d/90-gpio.rules with:

KERNEL=="gpiomem", OWNER="root", GROUP="gpio"
Create the group itself and assign it to an existing user "pi":

sudo groupadd -f --system gpio
sudo usermod -a -G gpio pi
