Implement File Recovery Plugin

[avizack18]

Hi there,

This feature request proposes the addition of a file recovery plugin to dissect. This plugin would enable users to recover accidentally deleted files from target device.

We have two main features planned that aid this functionality:

• Ability for filesystem implementations to mark files in a directory listing as "deleted"
  • This depends on #649
• More extensive scraping functionality and implementations that allow scraping for various things (artefacts, complete files, etc)
  • This is already partially implemented, but requires some love
