Fix CMS API endpoint and query builder

[hawyar]

Breaking change from CMS!

The CMS API domain changed causing this package to break. We need to update the API endpoint as well as the query builder that constructs filtering, limiting, grouping, etc.

• Update endpoint fromhttps://data.cms.gov/resource/{dataset_id} to https://data.cms.gov/data-api/v1/dataset/{dataset_id}/data

• Update the query builder to follow Drupal JSON:API module.

Example of the new url with filters:
https://data.cms.gov/data-api/v1/dataset/b8b0419c-3025-4738-8787-ed40c9e0816d/data?size=5&distinct=true
