Deep folders scan

[Refloow]

Currently the way exiftool implementation works it checks only 1 folder, one assigned, but not folders and subfolders and all files inside of that 1 folder. It should do that otherwise a lot of evidence might be missed

The current way should be as a feature, and this being deep scan as a togglable thing so user can select if they want to analyze just this one foldedr or alaso all subfolders
