PS4 Release: pkg_pfs_tool by flat_z

PS4 veteran developer flat_z has released pkg_pfs_tool, a set of tools that can unpack PKG/PFS Files, build GP4 projects, and generate the required keys for PS4 pkg file manipulation (unpack/repack).

The tool is released in memory of scene dev Maxton, who sadly passed away this year.
