feat: add Twitter support

[artdude543]

• Now, this is not really ideal as we're now using another OAuth lib. But it does open some more doors for interfacing with other API's.
• The main issue with Twitter and you'll see the hack in the code is the transferring of the state query. So it's allowed to be given the end handler. There could be other ways of handling it but this worked for the usage case for now.
  • I'm removing the key store in error handling. But I may be missing some cases.

But this adds much-needed support for me and avoids having to use another lib hander. Suggestions welcomed!
