checkdmarc 5.14.3

on Python PyPI

Fixes

• Fix type of approved_mx_hostnames parameter in check_domains (closes #238)
• Resolve Pyright/Pylance type errors and warnings across the project:
  • Use Literal[True]/Literal[False] for valid in DMARCResults /
    DMARCErrorResults to enable discriminated union narrowing
  • Make nameservers parameter Optional in check_mx, get_mx_hosts, and
    get_tlsa_records to match call sites and the underlying query_dns
  • Type get_nameservers return as NameserverResultOk; type the error path
    in check_ns as NameserverResultError
  • Type parsed_dmarc_record in parse_bimi_record / check_bimi as
    Optional[Union[DMARCResults, DMARCErrorResults]]
  • Type results_to_json, results_to_csv, and results_to_csv_rows inputs
    as DomainCheckResult | list[DomainCheckResult]
  • Remove stray tuple wrapper around an add_argument call in the CLI
