Version 4.0.0

• The Refit library has been removed because it produces a client implementation which is not Aot compatible and won't be for the forseeable future.
  • Refit has been replaced by a custom Source Generator which creates a client implementation at compile time.
  • The public Api of the IDiscogsApiClient has not been changed and updating will not break existing code.
  • Json serialization has been replaced with a source generated DiscogsJsonSerializerContext.
  • The Refit ExceptionFactory implementation has been moved into a ErrorHandlingDelegatingHandler middleware.
  • Added Demo project for an Aot publishable console application using the DiscogsApiClient.
• The authentication flow for OAuth has been changed.
  • The single call to AuthenticateWithOAuth using the GetVerifierCallback has been removed.
  • It's been replaced with the two calls StartOAuthAuthentication and CompleteOAuthAuthentication.
  • With this change the OAuth authentication can be handled more linearly instead of with a callback function.
  • The HttpClient used by the OAuthAuthenticationProvider now also uses the ErrorHandlingDelegatingHandler middleware.
