Rollups meta step

[stephenctw]

Depends on cartesi/machine-solidity-step#74 to pass the tests

[stephenctw]

An rollups integration test is added with a Lua orchestrator script which does the following:

• spawn an Anvil blockchain
• deploy necessary smart contracts
• spawn an honest Rust Dave rollups node
• send some inputs
• spawn several Lua sybil nodes

Although the code may seem working fine, I still think we need to:

• write a explorer tooling to monitor
  • what time does the tournament close
  • what's the current dangling commitment
  • list all dead commitments
  • and how many active matches, etc.
• carefully review all the math/logic in the commitment calculation
• test more sybil combinations/edge cases (uarch-reset, send-cmio) at meta-step call
• polish the code with better engineering practice
• more/better unit tests and coverage

To run the integration test with the following steps:

• run make test-echo from the prt/tests/rollups directory, this will print all Lua logs, including the sybil players and the orchestrator
• run docker exec rollups-echo-test tail -f dave.log on a separate terminal to see the logs produced by Rust Dave rollups node
