Split large news banners into 1x and 2x versions

[Walavouchey]

scaled down images that don't have 2x versions where width >= 1800 (arbitrary) by half, while renaming the original versions with @2x suffixes

excluding some old images that weren't designed to be banners, such as

• wiki/shared/news/banners/TWC_2015.png
• wiki/shared/news/banners/owc_2014.png

csv file of news banners missing 2x versions

nushell script

let large_banners = open missing_2x.csv | into value
    | where not is_external
    | where width >= 1800
    | where path !~ "TWC_2015.png"
    | where path !~ "owc_2014.png"
    | where path !~ "combat-championship"

    let p = $row.path | path parse
    let path_2x = $"($p.parent)/($p.stem)@2x.($p.extension)"
    mv $row.path $path_2x
    ffmpeg -v error -i $path_2x -q 2 -vf scale=w=in_w/2:h=-1 $row.path
