const DevMappingPosition = 2

DevMappingPosition is the position of the state variable `devs`. Since the state variables are as follows:

   bool public initialized;
   bool public devVerifyEnabled;
	  bool public checkInnerCreation;
   address public admin;
   address public pendingAdmin;

   mapping(address => bool) private devs;

   //NOTE: make sure this list is not too large!
   address[] blacksFrom;
   address[] blacksTo;
   mapping(address => uint256) blacksFromMap;      // address => index+1
   mapping(address => uint256) blacksToMap;        // address => index+1

   uint256 public blackLastUpdatedNumber; // last block number when the black list is updated
   uint256 public rulesLastUpdatedNumber;  // last block number when the rules are updated
   // event check rules
   EventCheckRule[] rules;
   mapping(bytes32 => mapping(uint128 => uint256)) rulesMap;   // eventSig => checkIdx => indexInArray+1

according to [Layout of State Variables in Storage](https://docs.soliditylang.org/en/v0.8.4/internals/layout_in_storage.html), and after optimizer enabled, the `initialized`, `devVerifyEnabled`, `checkInnerCreation` and `admin` will be packed, and stores at slot 0, `pendingAdmin` stores at slot 1, so the position for `devs` is 2.
