change yaml parsing engine to parse RC's atomic testing yaml format

ref: https://github.com/redcanaryco/atomic-red-team/blob/yaml-cs/atomics/spec.yaml

since RC has lots of support and time to dev - create a branch that will support RC's yaml format.

ideally this will take over as the go-to format
