community/loupe: upgrade to 46.0
Probably need Glycin 1.0 which still hasn't had a final release: https://gitlab.gnome.org/sophie-h/glycin/-/tags
Opening images seems to be broken. Should try again with Glycin 1.0.
This seems to work okay on my aarch64 Librem 5, but the image loading process crashes on my armv7 Samsung Galaxy Note 10.1 LTE. I think we probably can merge this as-is and investigate armv7 issues separately.
