`SetEACL` method of latest `Container` contract accepts binary session token as an argument. Provide `SetEACLArgs.SetSessionToken` method. Accept session token as a `[]byte` in `Wrapper.PutEACL` method and attach it to `SetEACLArgs`. Marshal session token from container in `wrapper.PutEACL` function and pass it to the method.
