[SRU] plasma-wallpaper-dynamic has relatively high memory usage

[Erich Eickmeyer]

[Impact]

 * A bug was discovered by the upstream author of plasma-wallpaper-dynamic which some wallpapers
   were causing high memory usage after being converted from Apple when used in multi-monitor
   setups.

 * This affects users of Ubuntu Studio where it is installed by default and Kubuntu users that
   may have this plugin installed and in-use.

 * Since this is a very narrow fringe set of users, this bug has a very minimal impact, but is a
   bug nonetheless

[Test Case]

 * Convert a wallpaper from the Apple format to the generic HEIC format.

 * Use on multiple monitors

 * Memory usage will be higher than using standard wallpapers on KDE Plasma.

[Regression Potential]

 * Since this is a plugin for KDE Plasma, there is some potential for regression in the desktop
   wallpapers. However, since this is a fringe case, and such a small diff, this is highly
   unlikely.

The Hirsute Hippo has reached End of Life, so this bug will not be fixed for that release.
