Add a CLI tool to deploy the contracts using Foundry (#86)

`deploy` can be launched with `--help` to see its documentation:

```
$ ./deploy --help

deploy - deploy the Liquity contracts.

Usage:
  ./deploy [NETWORK_PRESET] [OPTIONS]

Arguments:
  NETWORK_PRESET  A network preset, which is a shorthand for setting certain options
                  such as the chain ID and RPC URL. Options take precedence over
                  network presets. Available presets:
                  - local: Deploy to a local network
                  - mainnet: Deploy to the Ethereum mainnet
                  - tenderly-devnet: Deploy to a Tenderly devnet
                  - liquity-testnet: Deploy to the Liquity v2 testnet


Options:
  --chain-id <CHAIN_ID>                    Chain ID to deploy to.
  --deployer <DEPLOYER>                    Address or private key to deploy with.
                                           Requires a Ledger if an address is used.
  --ledger-path <LEDGER_PATH>              HD path to use with the Ledger (only used
                                           when DEPLOYER is an address).
  --etherscan-api-key <ETHERSCAN_API_KEY>  Etherscan API key to verify the contracts
                                           (required when verifying with Etherscan).
  --help, -h                               Show this help message.
  --open-demo-troves                       Open demo troves after deployment (local
                                           only).
  --rpc-url <RPC_URL>                      RPC URL to use.
  --verify                                 Verify contracts after deployment.
  --verifier <VERIFIER>                    Verification provider to use.
                                           Possible values: etherscan, sourcify.
  --verifier-url <VERIFIER_URL>            The verifier URL, if using a custom
                                           provider.

Note: options can also be set via corresponding environment variables,
e.g. --chain-id can be set via CHAIN_ID instead. Parameters take precedence over variables.
