Original GitHub issue: https://github.com/aome510/spotify-player/issues/908

Describe the bug
In the FreeDesktop Icon Theme Specification the only defined icon formats are PNG, SVG, or XPM, not JPG. This is important as this specification is also referenced in the notification spec.

To Reproduce
Use a strictly compliant notification daemon such as fnott.

Additional context
To workaround this, the icon can be encoded into PNG and sent as a notification. However, the notify_rust crate does not allow this, as it does not permit accepting a raw array of bytes. The only other solution would be to clear the image cache directory and download images as PNG moving forward.
