To dos left [ ] add run with latest c++ [ ] see if sonarcloud will play nice with gh actions [ ] r builds

any other bindings ? or does the above list complete it

I think Manylinux builds should go on that list. And documentation of the CI. I have some small beautifications that I'd like to do, but not a priority.

Others that may need to be added: [ ] MatLab bindings? [ ] Coverage?

can I close this as we have a huge amount of continuous integration
