New version of macrel released (v1.6.0)

The biggest change is internal, using a much better approach to saving and loading models (thus removing the dependency on particular versions of scikit-learn)

A few other bugfixes were included

Want to make some new conceptual graphics.

Tried to give Powerpoint's AI 'copilot' a spin. Asked it to make me a slide with 100 circle shape objects randomly distributed. Was excited when it made me a pptx to download...

except this is what it came up with.
