FEAT: PAR ID refs in api and schema (#53)

* FEAT: PAR ID refs in FormatFamily arrays

- changed BusinessRule.formatFamilies and FormatFamily.formatFamilies in `api/par-api.yaml`;
- added missing formatFamilies property FormatFamily in `schema/types.json`; and
- changed BusinessRule.formatFamilies in `schema/business-rule.json`.

* FIX: Update examples repo.
