Release 2.1.0

• Ensures that the company and city parameters are properly encoded when querying the Sirene API.
  This fixes potential issues with special characters in these fields, leading to more reliable search results.
• Improves search functionality by adding support for searching by the establishment's usual name.
  This change introduces the 'cue' (denominationUsuelleEtablissement) field to the search parameters.
  It also modifies the query construction logic to properly handle the 'cue' field by wrapping it within a 'periode' clause.
