Missing support that's potentially blocking broader adoption in GNOME

[sophie-h]

As discussed in Matrix before, there we are thinking about using this tiff crate basically everywhere in GNOME. Right now it's only used by Image Viewer (Loupe), and people can still fallback to apps like Eye of GNOME to open images that are not supported by the tiff crate. That option would then be gone.

The following issues have been reported by users that were able to open them with other apps:

• CCITT Group 4 / T.6 "fax machine" Possible Group 4 decoding with fax crate? #157 (closed as not planned)
• "invalid code in LZW stream" Loading fails with "invalid code in LZW stream" #231
• Cannot open Tiff Black and white chanel Cannot open Tiff Black and white chanel #259
• cannot open JPEG encoded TIFF with alpha channel Cannot open JPEG encoded TIFF with alpha channel #260

This issue also sounds relevant since it's based on imagemagic output #183
