Some additional Ruff rules to consider / Code quality improvements

[Casper-Guo]

• Bugbear (B): better exception handling workflow and other gotchas
• Builtins (A): In our case, mostly using round as a variable name
• Trailing commas (COM): Lists shouldn't use trailing commas
• Comprehensions (C4): Mostly matter of preference but does warn about some unnecessary casting of generators
• Implicit string concat (ISC): This one can be especially helpful given that we use implicit string concatenation quite a bit to get around the line width limit, and they are quite mistake-prone
• Quotes (Q): We use a mix of single and double quotes. Having more consistency would be nice.
• Return (RET): Mostly matter of preference but occasionally save a lot of debugging headaches when one unintentionally returns None at the end of functions. If we use this we will ignore a big subset of the rules
• Unused arguments (ARG)
• pandas-vet (PD): Helps catching some methods no longer recommended by Pandas and/or subjected to future deprecation

Thoughts on these?
