[Feature Request] Tweet Source Labels

[AyeTSG]

As seen in irucabot/ReturnTweetSourceLabel, it's possible to use Twitter's GraphQL api to return tweet source labels as they used to be before the X-ification. I think it'd be worth it to add this as an option.

I propose that this feature be added to Control Panel for Twitter.

If proposal is accepted, I'm willing to do the implementation of this whenever I get free time to do so, and I'd submit as a new PR.
