fa69918124
This change introduces the `featurePermissionDelegationV1_1` amendment, which is designed to supersede both `featurePermissionDelegation` and `fixDelegateV1_1 amendments, which should be considered deprecated. The `checkPermission` function will now return `terNO_DELEGATE_PERMISSION` when a delegate transaction lacks the necessary permissions.
