Support Asymptote diagrams

[mgajda]

Fixes #55 by adding supported for Asymptote.

Thank you for your contribution!

Can you also modify the continuous integration script to install Asymptote? You'll also need to modify the 'integration tests' step to test pandoc-plot on issue55.md

The CI issues are with Python Bokeh.
I could not find an asymptote installation GitHub action, so it is hard to test.

[mgajda]

@LaurentRDC I have added installation instructions for Asymptote using apt-get on Linux, Chocolatey on Windows, and Homebrew on MacOS.

Please let me know if it runs :-)

[mgajda]

It seems that Asymptote works on all platforms.

If you approve this and #62, I may check how much to add to MacOS tests that would still work.

[mgajda]

Please merge!

1. I have added testing of all output formats for all available toolkits.
2. I have added declaring output format for Asymptote: PDF, EPS, and PNG work.
3. Unfortunately SVG, JPG output do not work in default Debian installation due to stringent ImageMagick security policy.

Previous round of tests was success with Asymptote on Mac:
https://github.com/LaurentRDC/pandoc-plot/actions/runs/6174543606/job/16759375009?pr=61#step:20:175
Unfortunately the executables are undetected on Ubuntu and Windows. For unknown reasons.

Since asymptote tests work now, I suggest we merge this, and I continue fighting CI in a separate PR.

[LaurentRDC]

I'm not merging until all the CI tests pass.

I committed earlier today and the tests all passed. Therefore, the source of breakage is in this PR.

Looks like some versions toolkits (e.g.MATLAB and ggplot2) installed in Github CI specifically don't support all save formats. E.g. I can save SVGs in MATLAB on my laptop, but apparently not in GitHub CI. Therefore, your update to the tests is too optimistic.

If you undo that change, I think the CI tests will all pass

[mgajda]

Thanks for feedback!

I agree that I should undo CI changes, and ensure all tests pass.

[LaurentRDC]

Can you remove commented-out commands?

[LaurentRDC]

This is looking really good. I've made one last comment to clean up the PR a bit and remove CI debugging commands.

Once that's done, I'll merge your PR.

[LaurentRDC]

I'll be cleaning up the PR directly in the master branch.

Thank you for your contribution!
