To get images with higher resolutions, the img_src can be calculated from the
thumbnail_src.
WIP:
The calculated img_src is not valid for all images, some calculated URIs will
end in a `Forbidden` response. I can reproduce it for example with a
`!deviantart dali` query: The URI that is calculated for the image with the
title `Dali - Pencil` results in a `Forbidden` response.
DEBUG searx.engines.deviantart : Dali - Pencil: /v1/fit/w_300,h_592 --> /v1/fit/w_648,h_1280
