Create a table comparing Soar to other distro agnostic package manager

[sbstn87]

Hi,

just a suggestion to create a table comparing Soar with different distro agnostic (or not) package managers. This would allow everyone to see what it offers, how is it better or worse versus different solutions trying to achieve the similar goals.

Suggested package managers to cover:

• Flatpak
• Snap
• AM Manager: https://github.com/ivan-hc/AM
• nix: https://github.com/NixOS/nix
• deb-get: github.com/wimpysworld/deb-get
• bin: github.com/marcosnils/bin
• homebrew
• pkgsrc: https://github.com/NetBSD/pkgsrc
