Script to automatically update JSON flavour list

[camball]

Use requests and selenium to automate the “see full menu” button, then bs4 to scrape flavours in a script and update the JSON.

Might have to do some manual validation though, for example when it says "Peach, Passion Fruit w/ Blackberry & Blue Raspberry Drizzle", that's kinda ambiguous at first glance. Had to look up a YouTube video to understand that that meant "the flavours are peach and passion fruit, and there is blackberry drizzle and blue raspberry drizzle."
