Add support for specifying separate addresses for non-inlinable libraries on different networks

🌟 Feature Request for hardhat-zksync plugin

💥 Plugin name

hardhat-zksync

📝 Description

Add support for specifying separate addresses for non-inlinable libraries on different networks in the compiler settings. Currently, non-inlinable libraries need to be deployed separately, with the address specified in the hardhat config. However, this single address setup poses issues when deploying to multiple networks, such as a testnet and mainnet, or different chains built with ZK Stack.

This new feature would allow users to provide a mapping with unique library addresses for each network, enabling seamless deployment to multiple targets without needing to manually change configuration files.

🤔 Rationale

This feature is essential for teams working with multiple deployment targets, as it ensures flexibility and efficiency when deploying to various networks. By supporting network-specific addresses, developers can automate deployments across different environments more effectively, saving time and reducing potential for error.

🖼️ Mockups/Examples

If implemented, the configuration could look like this:

module.exports = {
  solidity: "0.8.7",
  networks: {
    mainnet: {
      libraryAddresses: {
        SomeLibrary: "0xMainnetAddress",
      },
    },
    testnet: {
      libraryAddresses: {
        SomeLibrary: "0xTestnetAddress",
      },
    },
  },
};

📋 Additional Context

This enhancement would be particularly useful for projects utilizing ZK Stack or deploying across both mainnet and testnet environments. It provides a streamlined approach for managing library dependencies across various network configurations.
