Running the command pip3 install inky fails with the following output:

The issue appears to be related to the 'spidev' package, because running pip3 install spidev returns a similar error

macOS !?!?

I guess if you want to use the simulator or have the code locally for intellisense and such you can grab the source, delete this dependency and install it from the local files.

I don't think we can conditionally include a dependency in a way that doesn't make it overcomplicated for Pi/Linux users so this probably wont be fixed.
