feat: jxl support for gallery and preview

[Quackdoc]

Support JXL images in preview and thumbnail

Things that need to be solved first

• This is causing images not to render: error decoding with image-rs integration but not with jxl-oxide cli tirr-c/jxl-oxide#473
• I am using unwraps with the intention of having a place holder image as mentioned here [BUG] Details pane not showing image preview despite having thumbnailer support #515

Questions

Should I also wire up using a thumbnailer for the preview pane and perhaps even gallery view? Personally I don't think gallery view should use the thumbnail but preview should.

Should the gallery view not open or should it display a place holder image? A placeholder image could show a "non compatible image" format which may be more user friendly then not opening the gallery at all.

Should I change thumbnailer to use a similar function (see below) or use the nested matches for gallery and preview?

jxl" => {
                    let jxldynimg = (|| {
                        let file = File::open(path).map_err(|err| {
                            log::warn!("failed to open file {:?}: {}", path, err);
                        }).ok()?;
                        let mut limits = image::Limits::default();
                        let max_ram = max_mem * 1000 * 1000 / jobs as u64;
                        limits.max_alloc = Some(max_ram);
                        let mut jxl = JxlDecoder::new(file).map_err(|err| {
                            log::warn!("to create JxlDecoder for {:?}: {}", path, err);
                        }).ok()?;
                        let _ = jxl.set_limits(limits);
                        Some(image::DynamicImage::from_decoder(jxl).map_err(|err| {
                            log::warn!("failed to decode the file {:?}: {}", path, err);
                            }).ok()?
                        )
                    })();
                    //TODO: This will be unwrap_or(generic image)
                    jxldynimg
                }

With decoding hooks, tirr-c/jxl-oxide#480 comming up I will use this instead when it lands, I won't close this for now.
