Check if a string is a valid Ethereum address with EIP-55 checksum validation

import { Address } from '@tevm/voltaire/Address';

// Valid checksummed address
const validAddr = "0x742d35Cc6634C0532925a3b844Bc9e7595f251e3";
const isValid = Address.isValid(validAddr);

// Invalid checksum
const invalidChecksum = "0x742d35cc6634c0532925a3b844bc9e7595f251e3";
const hasValidChecksum = Address.isValidChecksum(invalidChecksum);

// Not an address
const notAddress = "0x123";
