openEO Python client v0.5.0

Added

• Add namespace support to DataCube.process, PGNode, ProcessGraphVisitor (minor API breaking change) and related.
  Allows building process graphs with processes from non-"backend" namespaces
  (#182)
• collection_items to request collection items through a STAC API
• paginate as a basic method to support link-based pagination
• Add namespace support to Connection.datacube_from_process
• Add basic support for band name aliases in metadata.Band for band index lookup (EP-3670)

Changed

• OpenEoApiError moved from openeo.rest.connection to openeo.rest
• Added HTML representation for list_jobs, list_services, list_files and for job results
• Improve refresh token handling in OIDC logic: avoid requesting refresh token
  (which can fail if OIDC client is not set up for that) when not necessary (EP-3700)
• RESTJob.start_and_wait: add status line when sending "start" request, and drop microsecond resolution from status lines

Fixed

• Updated Vue Components library (solves issue with loading from slower back-ends where no result was shown)
