Reading foreign state

This example demonstrates the verification of the total supply of USDC on Optimism from Gnosis Chain using a storage proof. The proof will be fetched via HashiAPI and fed to a contract deployed on Gnosis Chain. The contract will use HashiProver to validate the proof against the last Optimism reported block header stored in Hashi.
