Help needed with plaso/dfvfs and their dependencies

[Raphael Hertzog <hertzog@debian.org>]

Hello,

I wanted to help a little bit to fix #971311 & #971308 related to
the deprecation of PyCrypto but I have opened a can of worms.

We need to package new upstream releases of dfvfs and plaso to fix those
(and other RC bugs like #971149). But the new dfvfs requires 4 new packages:
  * python3-libfsext: https://github.com/libyal/libfsext
  * python3-libfshfs: https://github.com/libyal/libfshfs
  * python3-libfsxfs: https://github.com/libyal/libfsxfs
  * python3-libluksde: https://github.com/libyal/libluksde

The new plaso and dfvfs also bumped the minimal version of many
dependencies that we should update too.

It would be nice if someone could help here. I'll happily sponsor uploads
if needed.

Regards,
