Clifford Synth and Readme update

[daehiff]

TL;DR: This PR adds the code from arxiv.org:2309.08972 for our Clifford tableau synthesis algorithm and some improvements on the CI and README.md.

README.md:

• Removed the images for readability
• Added list of algorithms we are currently supporting
• Refactored smaller examples

Clifford Tableau Synthesis:

• General implementation combined with code cleanup
• added documentation
• added minimal working sample in the README.md

Can I get some colour on why this one was closed, as opposed to merged?

[daehiff]

Missclick, to be honest, I'll integrate the circuit class of @y-richie-y and then reopen it.

Sorry :D

Good to know: it seemed to be a lot of work to just drop it 😊. I'll reopen it now to keep track of things, you take all the time you need.
