Unpack terraform manifests from crossplane terraform workspaces

This small utility extracts terraform workspaces managed by the crossplane terraform provider.

Crossplane terraform workspaces are reconciled only at runtime or aka by the cluster. However it is good practice to validate things beforehand. This utility extracts terraform resource from crossplane managed workspaces which makes it possible to run things like terraform fmt and terraform validate beforehand.
