Should holders have to authorize themselves to updateLandData? about land

[nachomazzara]

Agree, we may need to change the modifier of the _update function from

function updateLandData(int x, int y, string data) public onlyOperator(x, y) {
    return _update(encodeTokenId(x, y), data);
  }

To

function updateLandData(int x, int y, string data) public onlyOperatorOrHolder(x, y) {
    return _update(encodeTokenId(x, y), data);
  }```

Good catch!

Agree, we will change the modifier to support Operators and Holders.
