how to store abi on smart contract and decode it.

[novaknole]

Hi ^_^

I have a function in the smart contract that I want users to override.

function deploy(bytes memory data) {

}

When users inherit this, UI has no idea what data is, so I am in a need to store the ABI on the smart contract as well, such as:

function deployABI() external view returns(string memory) {
    return "(uint _num1, address _addr)";
}

I am curious if ethers.js has any kind of transformer that can transform this into the actual ABI object... or what do you recommend ? storing the whole string abi inside deployABI is something I don't like, but human readable abi would be better, though I don't have function name as I can see in ether's human readable docs.

Thank you.
