DEV: Add upper limits for complexity

[cclauss]

If we set upper limits then if someone wants to contribute more complex code then they need to justify in their pull request why they need messier code than is already in the codebase.

[tool.ruff.mccabe]
max-complexity = 54  # Recommended: 10

[tool.ruff.pylint]
allow-magic-value-types = ["bytes", "float", "int", "str"]
max-args = 12  # Recommended: 5
max-branches = 36  # Recommended: 12
max-returns = 11  # Recommended: 6
max-statements = 176  # Recommended: 50

I agree that we should gradually converge to a codebase that is easier to read/understand, maintain, and extend. Thank you 🤗
