Integrate dagger contracts from `nim-dagger-contracts` repo. Add `dagger-contracts`, `nim-web3`, and all of `nim-web3`’s transitive deps as submodule deps to `nim-dagger`. Note: `nim-web3` and its transitive deps may no longer be needed when we switch to `nim-ethers`. Add a `testContracts` nimble task to test all of the contracts functionality. Namely, this spins up an ethereum simulator, deploys the contracts (in `dagger-contracts`), runs the contract tests, and finally, regardless of success/error, kills the ethereum sim processes. The nimble task can be run with `./env.sh nimble testContracts`. We also tested `nim-dagger-contracts` as a submodule dep of `nim-dagger`, and while the tests run as expected, the preference is to merge `nim-dagger-contracts` inside of `nim-dagger` for ease of parallel development. There’s also a high probability that `nim-dagger-contracts` is not being used as a dep by other projects. Are there any strong objections to this?
