feat: add model thumbnail support

certain games may opt to use roblox-generated thumbnails as decal textures.
since we're already using the roblox thumbnail api, we can pipe `/Thumbs/Asset.ashx` through
there too.

obviously, due to old assets, certain games may not have those assets correctly rendered.
a good example would be work at a pizza place, which used to utilize the pizza model thumbnail
as the cashier button. its model has since changed, so now all 3 pizzas appear the same.
but you can always either modify the place itself or replace the rbxthmb asset in the cache.
