    CI: Ignore flake E226 error
    
    E226 says that "There should be one space before and after an
    arithmetic operator".
    This error is disabled on a default flake8 configuration (the --ignore
    flags overrides it) because it is not PEP-8 compliant.
    
    The main argument against this rule is that it obfuscates complex
    arithmetic operations.
