Quick-and-dirty scraper that checks for the availability of a product in the Unifi store

I was unable to get the original script working, so I modified it. Instead of checking for an "add to cart" button, it
checks whether or not there is an "in stock" badge on the product page. I'm also using discord webhook to ping me whenever
the item comes in stock.

Requirements:
beautifulsoup4==4.10.0
requests==2.26.0
requests_html==0.10.0
tenacity==8.0.1
discord-webhook==0.17.0
