Informational: Arch Linux package.

Informational -- maybe you want to add it to your [`README.md`](https://github.com/anestisb/vdexExtractor/blob/master/README.md):

There is an [Arch Linux](http://archlinux.org/) package of this in the [AUR](https://wiki.archlinux.org/title/Arch_User_Repository): [`vdex-extractor-git`](https://aur.archlinux.org/packages/vdex-extractor-git).
