Tweet downloader cannot download some tweets due to Authorization, Cannot switch authorizations.

[HesitantlyHuman]

Currently, the tweet downloader should be switching between different Authorizations, but it seems to stop once it has used each a single time. May need to add more authorizations, or modify this logic. The TooFast error is not very helpful when someone is using the high level API and requires a significant context switch. (Maybe a better error message from the Tweet downloader as well?)

Additionally, there are some Tweet IDs for which the downloader does not receive any response from the Twitter API. After checking the V2 API, it looks like this is an authorization issue. I do not know why this is happening, and fixing it would almost double the training examples available for the Twitter datasets.
