Add VHD/VHDX Scanner

[ryanohoro]

Is your feature request related to a problem? Please describe.

Threat actors are using VHD/VHDX images in a manner similar to how they use ISO9660 images for email attachment delivery. Strelka has no support for VHD/VHDX.

Describe the solution you'd like

A scanner, similar to ScanIso, that supports VHD/VHDX images, can extract files, and report on image metadata, including timestamp, file system, and volume labels.

Describe alternatives you've considered

N/A

Additional context

There is very little native Python support for VHD/VHDX parsing and extraction, however the Ubuntu package 7zip supports VHD/VHDX.
