Describe the bug
The tray module is incorrectly rendering the color channels of the pixmaps provided by applications with tray icons.

To Reproduce
Steps to reproduce the behavior:

Update the config to include the tray module (very large icons make it easier to see)
```
type: tray
icon_size: 128
prefer_theme_icons: false
```
Observe the tray icon in detail, and notice that it does not appear the same as the original icon viewed in an image viewer.

Expected behavior
The tray icon should be rendered the same way an image viewer would.

System information:

Distro: Arch Linux
Compositor: Hyprland
Ironbar version: f4e1e81

Configuration

start: []
center: []
end:
  - type: tray
    icon_size: 128
    prefer_theme_icons: true

Additional context
The GTK documentation here shows that the internal representation of their pixel data is RGBA, instead of the ARGB data that's being handled by modules/tray/icon.rs::get_image_from_pixmap

Screenshots
