Rename O::L::C::W::Azure to O::L::C::W::AuthCodeFlow

Turns out there’s nothing strictly Azure-specific about it.

+=head1 NAME
+
+OIDC::Lite::Client::WebServer::AuthCodeFlow - extension to auth against an
+identity provider using the authorization code flow, such as Azure AD B2C or
+Google OAuth 2.0.
+More info: https://openid.net/specs/openid-connect-core-1_0.html#CodeFlowSteps
+
+OIDC::Lite doesn't appear to support the authorisation code flow to get an
+ID token - only an access token. This flow returns all its claims in the id_token
+(and may not support a UserInfo endpoint e.g. Azure AD B2C), so this extension
+adds support for parsing the id_token when calling get_access_token.
+
+=cut
+
+=head2 new
+
+Overrides response_parser so that get_access_token returns a
+L<OIDC::Lite::Model::IDToken> object.
+
+NB this does not perform any verification of the id_token. It's assumed to be
+safe as it's come directly from the OpenID IdP and not an untrusted user's
+browser.
