In this example, we will demonstrate how we can use `check_ecdsa_signature` to verify if (`signature_r`, `signature_s`) is a valid ECDSA signature for the given `public_key` Solidity reference: https://solidity-by-example.org/signature/
There is a problem with the example of solidity-compatible hashes. The way it's currently done is that it calls `keccak_u256s_be_inputs` to hash a span composed of u256 words - however...
