8.15.0

- Fix processing of SMTP-TLS reports ([#549](#549)), which broke in commit [410663d ](410663dbcaba019ca3d3744946348b56a635480b)(PR [#530](#530))
  - This PR enforced a stricter check for base64-encoded strings, which SMTP TLS reports from Google did not pass
  - Removing the check introduced its own issue, because some file paths were treated as base64-encoded strings
- Create a separate `extract_report_from_file_path()` function for processioning reports based on a file path
- Remove report extraction based on a file path from `extract_report()`
