Verify and/or add Raspi4 support

[SpottyMatt]

This should work on Raspi4 platforms running Raspbian Buster or later.

Rename the repo to raspiban-stepmania-arcade when done or create a new raspi-4-stepmania-arcade, depending.

While it's unlikely that new tech & updates will be built for Raspi 3 platforms (so maybe it's ok to just "move on" from Raspi 3 support), the embedded-device-ness of the Raspis means there may be folks trying to use Raspi 3 platforms for a very long time.

Did this in #8.

Just installing on a pi4 and used the buster+desktop only image. Running make seems to have a dependency on Wolfram. Is that correct?

That's likely happening as part of the apt-get update that happens before installation (as a matter of hygiene). wolfram-engine and wolframscript seem to be bundled with the Raspbian desktop.

If you apt install aptitude, you can then run aptitude why wolfram-engine --show-summary and you'll see that nothing depends on it - it's a top-level package that was installed.

I'll double check but I thought it was: sudo apt-get install --fix-broken -y /tmp/stepmania.deb

I've run aptitude

pi@dancepi:~ $ aptitude why wolfram-engine --show-summary
Packages requiring wolfram-engine:
  stepmania-4b
pi@dancepi:~ $ aptitude why wolfram-engine --show-deps
i   stepmania-4b Depends wolfram-engine (>= 12.0.1+2019062401)

Oh interesting.

I'll dig into that.
