Package doesn't declare dependencies

[tilusnet]

This package should declare all library dependencies. I don't think it does. Eg: spidev, numpy, etc. won't get installed if someone installs this library.

In https://github.com/pimoroni/pirate-audio there is an entry for that. Missing here though.

sudo apt-get update
sudo apt-get install python-rpi.gpio python-spidev python-pip python-pil python-numpy

Not sure if this is necessary but the explicitly python3 version of that is

sudo apt-get install python3-rpi.gpio python3-spidev python3-pip python3-pil python3-numpy
