Output files and supervisor deployment changes

[trkks]

NOTE: These changes depend on https://github.com/LiquidAI-project/wasmiot-modules/pull/15

I successfully tested the changes in the following ways:

• Simple fibo
• subtract -> fibo on a single device
• take_image_predefined_paths using host webcam
• infer_predefined_paths
• subtract -> fibo with the functions running on two separate devices
• take_image_predefined_paths -> infer_predefined_paths with the functions running on two separate devices
