[PRQ#50214] Deletion Request for imlib2-heic

MarsSeed [1] filed a deletion request for imlib2-heic [2]: Unneeded addon to imlib2, as now extra/imlib2 builds with HEIC/HEIF support via libheif. This was only useful earlier, when imlib2 itself did not use libheif yet. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/imlib2-heic/
