Add support for friend invites

[neu-ma-tic]

Friend invites are now available via the API, and may be released soon in the client. Currently, invidget just times out, rather than properly displaying the friend invite.

ex: https://invidget.switchblade.xyz/ZdErpjfX

how it looks in the discord client

---

invidget would need to get the data about the user via the inviter property of the invite itself, since there is no guild. The full API data is shown below.

/api/v9/invites/ZdErpjfX

{
  "code": "ZdErpjfX",
  "inviter": {
    "id": "921120740567314502",
    "username": "neu",
    "avatar": "1b9344fd45ded05c436a83db752d9701",
    "avatar_decoration": null,
    "discriminator": "1337",
    "public_flags": 0
  },
  "channel": null,
  "type": 2,
  "expires_at": "2022-07-01T16:43:29+00:00"
}

(to make a user invite, post to /users/@me/invites) this may be considered as selfbotting, so not recommending it!!!

(also i may work on this as a pr if i find some time to do it, but likely not)

Hi! I'm gonna take a look this week with the new api version, I didn't knew that discord already updated it. Thanks for letting us know 🎉

PS: That would look amazing on README's or websites
