tricolour cab crashes in 0.2.0

[tmolteno]

The tricolour cab seems to have issues similar to crystalball:

This is running under python3.8. I get the following

Looks like incompatibility between a system installed scipy. The tricolour package may need to move to pyproject.toml and also be installed in a virtualenv?

Yep, same story. Except scipy is an explicit dependency this time, so this is a pip fail. I'll push an updated image shortly.

[o-smirnov]

OK try now?

[tmolteno]

Still failing. I'm having a go at bringing tricolour up to date. Will also add an end-to-end test.

How's it looking now? The latest 0.2.0 image runs for me (or at least displays help).
