// LoadScript loads the given bytecode into the VM and executes it with the

// it's not a deployed contract that can have methods. The execution context is
// limited to read only actions ([contract.ReadOnly]) irrespective of provided
// call flags (you can only restrict them further with this option). An item is
// always returned from this call, either it's the one returned from the script
// (and it can only return one) or it's a Null stack item if the script returns
// nothing. Note that this is somewhat similar to [contract.Call], so the
// script can ABORT the transaction or THROW an exception, make sure you
// appropriately handle exceptions if bytecode comes from untrusted source.
