Proper compilation view

[gwwatkin]

latticesurgery-com/lattice-surgery-compiler#57 introduces a hacked view to show the stages of the compilation rendered as ascii text. (Example)

We want to be able to visualize circuits and Pauli rotations properly. For circuits we could use directly qiskits' rendering tools: https://qiskit.org/documentation/tutorials/circuits_advanced/03_advanced_circuit_visualization.html , which we already are using for ascii rendering anyways, and look good:

As for pauli rotations I guess we could come up with something that looks like Litinski's:

Or perhaps we can look deeper into quiskit's rendering, there might be something there we can use for pauli rotations?

Moving this to web-ui as we are separating the Web UI and Compiler repo.
