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.

[cpietsch]

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

[johnbchron]

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

Is there a reason that these requirements are "hidden" in the documentation, rather than being declared in a machine readable manner?

It is usually expected that, the following would work:

historically yes

now? Not so much!

small stuff-up on my part
