Full filename image URLs don't always exist for Philomena boorus

[Twi-Hard]

A very large number of images have failed to download because the long version of the view URL 404s

For example, this image:
https://manebooru.art/307071

gallery-dl tries to download this url:
https://static.manebooru.art/img/view/2020/10/27/307071__safe_artist-colon-kty159_character-colon-lyra+heartstrings_character-colon-pinkie+pie_#1_foam+finger_micro_question+mark.png.png

when it should probably be downloading the short url:
https://static.manebooru.art/img/view/2020/10/27/307071.png

Looking at the API, the short url is there under "representations"

I'm sorry about bringing so much stuff up. I try to bring things up in bursts then take a long break before asking about anything else.
