Rewrite of paramak from the ground up

[shimwell]

Just to mention I've starting a rewrite of paramak and am starting from scratch.

There are several reasons for this but the main few are

• First I'm better at programming now and can do a much better job of architecture the package.

• Since starting CadQuery and the CadQuery environment has as improved to include assemblies and other features that a new refactoring can make use of

• Conversion to DAGMC geometry has also progressed with conda forge packages for making the environment easier to install. We can make use of these and package the paramak of conda forge to make installation easier.
