MVP-006: Add SerpApi to autofill image descriptions when they first get uploaded

[pjpscriv]

Spun out from MVP-003, SerpApi has a reverse image search to get descriptions of uploaded item images.

Two parts needed for this:

• a backend endpoint that takes the image, makes the call to serPapi, then returns the description data
• front end logic when the image is uploaded that makes the call to the backend, takes the returned data and auto-populates the item data

Backend time babeeee

I have a slight counter-proposal to the original reverse image search idea:

What if we used a Custom Search Engine Image query instead so that the user only has to search a keyword(s) of the image they want to add to their Tierlist.

• For example, you want a picture of Darth Vader for your Star Wars characters Tierlist. Searching "Darth Vader" will shift the results (Image URLs) into the cropper from MVP-002 and the user can select their favorite image and crop it to their liking AND the other information (title, description, and a link to relevant site - in this case probably a Star Wars wiki) will autofill from the JSON query results. Designs for this example 👀

Thoughts?

Future cases could allow storing the query result in the category (Star Wars or Sci-Fi Category) and auto-filling the image search keyword using a prefix trie from the Tierstra backend before running an expensive SERP query...
