[FEATURE REQUEST] Add MITRE ATT&CK techniques to modules

[Cx01N]

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

MITRE introduced subtechniques to the ATT&CK framework, and Empire has yet to integrate those into the modules. It would be great if someone could add subtechniques to existing modules.

Describe the solution you'd like

Research subtechniqies and find out which ones match with existing modules.

Describe alternatives you've considered

We can not use sub technique mapping.

Additional context

Use similar formatting for subtechniques as techniques and software.

subtechniques:
 - T1547.001

Subtechnique example:

I would recommend if anyone starts on this issue to start with 1-2 modules and comment here which ones you are starting to reduce overlap.
