refactor: try to integrate jpegxl_rs with hooks
The problem is, libjxl_rs does not offer a way to get metadata
before decoding the entire image.

As such, there is no reasonable way to implement ImageDecoder here;
I think it's possible to make it decode the image on init,
but that would lead to unexpected behavior performance-wise.

# imagey
image viewer and maybe editor; inspired by mpv's simplicity
name is subject to change, suggestions welcome :)
## usage
```sh
# try it out!
nix run git+https://git.federated.nexus/electria/imagey
# install it imperatively
nix profile install git+https://git.federated.nexus/electria/imagey
```
keybinds are shown on startup if you didn't start it with an image
## known issues
### JXL
1. encoding is not implemented (jxl-oxide is decoding-only)
2. oreintation is incorrect in some cases
if the image has metadata oreintation AND
it's a jxl without the right extension OR
it's a jpeg with the jxl extension
this is due to the JXL decoder automatically rotating the image,
while the JPEG decoder (for instance) requires the extra step.
my workaround is to check the path of the input file,
not changing the oreintation if it has the jxl extension;
causing these caveats for cases where the extension is wrong.
### clipboard
1. large images (eg photos) don't seem to copy on linux/wayland,
(despite set_image not returning any error)
