FR: "Explore" mode to search a file system for web artifacts

[obsidianforensics]

Lots of mobile, IoT, etc devices use Chromium-based components, but they aren't structured in the file system exactly like Chrome. Hindsight currently uses this directory structure to determine what files to parse. It would be cool to have a mode where Hindsight walks the file system and examines each file to see if it knows how to parse it, regardless of file name or logical location. I think having this in a separate mode makes sense, rather than building it into the default way it works (but that may change if it works well).
