moving to new CQ export method

[shimwell]

Proposed changes

This removes the opening of a file and use of exporters.exportShape and replaces it with exporters.export as discussed in #82

The former is now depreciated.

The new option will also support additional SVG options via an opt keyword once CQ 2.1 is released

Also slightly more control over the stl export is also offered via the introduction of a new argument called angular_tolerance

This looks like a nice addition to make things more tidy!

[shimwell]

Not sure why this is failing, I've tried switching back to the original stl export and changing pymoab to the main branch but the github actions CI are still failing

[shimwell]

I need to redo parts of this PR as #718 has updated the svg export

[shimwell]

closing this a #720 #718 and #721 have added the features
