Today PlayStation 4 developers @RedEyeX32 (Twitter) and @SpecterDev (Twitter) announced a new project they've been working on aimed at locating PS4 PKG files known as the PlayStation 4 Package Finder! 
Similar to the PS4 Package Database for Games, Apps and Themes or Fenny's List this project allows searching by the PS4 game's Title ID (PS4_GameDump_TitleEditor.rar - 96 KB) and environment including NP, SP-INT, PROD-QA, MGMT, E1-NP, and RC.
To quote from their OrbisModding.com site: Welcome!
This is the PlayStation 4 PKG Finder, developed by Red-EyeX32 and Specter. Simply put the game's title_id into the search below and the site will find information about the given title, including if the latest patch is mandatory, the minimum system version, content_id, update(s) size, and latest package links!
Cheers to @raedoob in the PSXHAX Shoutbox for the heads-up!
