[PRQ#42626] Deletion Request for mpfc

MarsSeed [1] filed a deletion request for mpfc [2]: CLI music player discontinued 9 years ago. Cannot be built because it needs the also-discontinued 'gpm' go package manager, nowhere to be found now on Arch/AUR. (Arch core/gpm and AUR gpm-vm and gpm-git are for a totally unrelated software.) Not needed: there are several working alternatives for command-line audio players. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/mpfc/
