Test generalized Pauli matrices

[atomgardner]

We add tests to check the creation of generalized Pauli matrices. Fixes #485.

Hi @atomgardner, thank you for both of your PRs.

I just wanted to point out that even though the issue is tagged unitaryhack, the monetary award related to fixing an issue is only available when unitaryHACK 2024 starts (May 29 -June 12).

We tagged the issues pretty early because we didn't want to accidentally assign these issues to ourselves. I'll go ahead and remove the labels as it might cause additional confusion.

Edit: Did you use black to format your code? It is not compatible with our ruff configuration file, FYI. For example, we allow line-length > 80 which is the default setting for black.

@purva-thakre, haha, I'm happy to bear some responsibility here—I'd misread the unitaryHACK dates, this was the first repo I'd clicked on, and the tags made it seem like I was already late to the party.

re style: no black; I ran ruff format before pushing.

[vprusso]

Sincerely appreciate the ownership, @atomgardner !

It appears as if the black formatter is still forcing the lines of the test files to aggressively new line. The thing is that applying ruff after black won't revert the black formatting. Hope that makes sense, and of course, feel free to let me know if we can provide any help / clarification / etc!

[atomgardner]

@vprusso haha :)

So, I minified the matrices and ran ruff check, and it did lead to a different formatting. How does this look? (Plus, how did you catch this in the first place?)

[vprusso]

LGTM! As @purva-thakre said, we hope to see you around for UnitaryHack, @atomgardner !
