"Rate limit" users when making requests

I think we need to add a temporary stop-gap to prevent users from generating playlists too quickly, so we do end up hitting Spotify's rate limit and crashing the app for them (and potentially other users; I'm not sure if one person being rate limited actually limits others or not).

The first thing that comes to mind was just to store some kind of "lastGeneratedTime" cookie in the browser which is checked before generating and only allows a new generation if, say, more than 2 minutes has passed.

I feel like this is the best way to go about this. Although I do feel like some users might find that annoying when they want to play around with parameters in the planned "advanced" mode (which I think has lower request rate?).

Ironically I'm not sure we'd need the rate-limiting on the advanced version.

The biggest load on the API there would be fetching a user's followed artists but that returns pages of, maybe, 50 artists at a time so you only need 4 requests for even following 200 artists.

After that it's maybe 2-3 more API calls to get the song recommendedations and then add them to the playlist.
