Ethereum integration for ProofPack with ES256K signatures, EAS attestations, and multi-network blockchain verification

# @zipwire/proofpack-ethereum

Ethereum integration for ProofPack with ES256K signatures, EAS attestations, and multi-network blockchain verification.

## Quick Start

```bash
npm install @zipwire/proofpack-ethereum
```

```javascript
import { 
    EasAttestationVerifierFactory, 
    ES256KVerifier,
    ES256KJwsSigner 
} from '@zipwire/proofpack-ethereum';

// Verify EAS attestations
const networks = {
    'base-sepolia': {
        rpcUrl: 'https://api.developer.coinbase.com/rpc/v1/base-sepolia/YOUR_API_KEY',
        easContractAddress: '0x4200000000000000000000000000000000000021'
    }
};

const verifierFactory = EasAttestationVerifierFactory.fromConfig(networks);
const result = await verifierFactory.verifyAsync(attestation, merkleRoot);

// Verify ES256K signatures
const verifier = new ES256KVerifier('0x1234567890123456789012345678901234567890');
const isValid = await verifier.verifyAsync(jwsToken, messageHash);

// Sign with ES256K
const signer = new ES256KJwsSigner('0x1234567890abcdef1234567890abcdef1234567890abcdef1234567890abcdef');
const signature = await signer.sign(payload);
```
