I've pinned the version here for now, should probably become configurable.

tfexec implements tfjson to read the state, hence the big changeset in this file.

Synthesizing a stack here to reduce the signatures of the generate functions.

Not sure if this is the best place to put it, probably not but, eh 🤷

I've just used go mod edit -replace and go mod tidy, stupid tools doing stupid things :P
This PR refactors the generator to use https://github.com/hashicorp/terraform-exec/ to execute the Terraform binary. This removes the need for the user to provide the Terraform binary as part of their runtime environment, allowing the generator to be used as a library with less friction.
