[PRQ#48677] Merge Request for chirp-hg

MarsSeed [1] filed a request to merge chirp-hg [2] into chirp-next [3]: The '-hg' packages are long defunct, as upstream has migrated to GitHub. But also those legacy packages are abandoned and unmaintained. There's no '-git' package, but 'chirp-next' is essentially equivalent, providing frequent snapshot updates. I mentioned this recommendation to users in a comment. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/chirp-hg/ [3] https://aur.archlinux.org/pkgbase/chirp-next/
