Thank you @thorstenfleischmann could you please add documentation as well? Extra bonus for adding tests :-)

Also please add yourself to the AUTHORS file.

While looking through your change I realized the log statements will cause a Lua error if token_type_hint is nil - and it shares this "quality" with the existing openidc_revoke_token function, wich I'll fix now.

Thanks @bodewig for your feedback!

I added a new block to the readme and one (very basic) test. It took me quite some time to get into the design of the tests.

Also please add yourself to the AUTHORS file.

Done
