feat(job_scout): add RSS adapter, automate BIS vacancies

- Generic RSS/RDF feed parser (handles RSS 1.0 namespaced items + RSS 2.0)
- BIS (Bank for International Settlements, Basel) promoted from manual-check
  to an automated source via its vacancies RSS feed — commutable from Bern,
  salary net of Swiss tax. Scout now 20 automated + 4 manual-check.
