Is your feature request related to a problem?

I would find it very useful to be able to build a NavLayer based on a Techniques list.

Describe the solution you'd like

As input, this script would take techniques (and some annotations or scoring), and it would then build a json from them.|

Describe alternatives you've considered

I'm experiencing the possibilities within the library but I fear it will requires crafting the JSON myself based on this : https://github.com/mitre-attack/attack-navigator/blob/develop/layers/LAYERFORMATv4_1.md#example
