v2.0.0

🥊 Refactor:

• This is now a fastify API using typescript.

✨ New features:

• A postman library available in the README to test api endpoints
• A fancy (😂) new name
• An adaptation to new OAuth 2.1 standards such as:
  1 - authorization_code grant type using a third party provider (github & google)
  2 - client_credentials grant type to authenticate registered clients (like front-end applications)
  3 - PKCE process for google authorization code flow
