Make deploy work for smart contracts that depend on a ZkProgram

[mitschabaude]

Current behaviour:

zk deploy berkeley
✔ Build project
✔ Generate build.json
✔ Choose smart contract
  The 'GameOfLife' smart contract will be used
  for this deploy alias as specified in config.json.
✖ Generate verification key (takes 10-30 sec)
  Error: GameOfLife.compile() depends on Program0, but we cannot find compilation output for Program0.
Try to run Program0.compile() first.

Our deploy script compiles the SmartContract itself, but is not smart enough to compile dependencies
