Support grabbing the full image for Tinami uploads, rather than the sample.
Getting the full image requires making a request like this:
curl -X POST \
-H 'Referer: https://www.tinami.com/' \
-H 'Content-Type: application/x-www-form-urlencoded' \
-H 'Cookie: Tinami2SESSID=<redacted>;' \
--data-raw 'action_view_original=true&cont_id=1087268ðna_csrf=<redacted>' \
https://www.tinami.com/view/1087268
Then scraping the <img> tag from the resulting HTML page.
If the post has multiple images, then we need to scrape and pass the
`sub_id` of the image too.
Fixes#2818.
This directory contains library code used through Danbooru. This includes things like defining API clients, dealing with
sources, parsing tag searches, storing and resizing images, and so on.
Many of the files here use the Service Object pattern. Instead of putting complex code in models or controllers, it goes
here, in plain old Ruby objects (POROs). This keeps models and controllers simpler, and keeps domain logic isolated and
independent from the database and the HTTP request cycle.
