Raise YfRateLimitError if Rate Limited

[dhruvan2006]

Changes

• New YfRateLimitError exception class, which is raised regardless of raise_errors
• Raises the above exception if the response from Yahoo! Finance returns 429 status code.

Usage

Tricky. Can test it with any yfinance function. Would need to spam Yahoo! Finance until you get rate limited. But here is an example of how it looks:

I'd like to see more comments from users, maybe crosspost this into relevant Issues.

Will this raise in case of issue #2185? If yes then definite merge. Btw this should raise regardless of raise_errors argument, the user needs to take immediate action! So revert the change to raise_errors.

Situation is different to a loop where one ticker is delisted, the loop should continue, this is why raise_errors exists

Yes it will raise for #2185, I was testing it. Changes to raise_errors reverted and rate limit will always be raised regardless.
