Cheatcode to make upgradeable contracts for Ferrum Team

How to structure the data (ERC1967-ERC7201).

1. Define the implementation slot. One slot per major version

     bytes32 internal constant _IMPLEMENTATION_SLOT_V1 = 0x360894a13ba1a3210667c828492db98dca3e2076cc3735a920a3ca505d382bbc;
     // This slot can be calculated using the following formula. The result is used as constant.
     // DO NOT use the calculation in the constant definition as there is no guarantee it may be executed.
 // keccak256(abi.encode(uint256(keccak256("ferrum.storage.QPERC20.001")) - 1)) & ~bytes32(uint256(0xff))

const elliptic = require('elliptic');
const EC = elliptic.ec;
const ec = new EC('secp256k1');

const digestHex = 'a02c88bd2a...';
const rHex = 'b086ec...';
const sHex = '00fd29...';
const vHex = 0x1c - 27;

const r = Buffer.from(rHex, 'hex');
