update README to reflect changes that, at the moment, I reverted to not use promises. This decision was made, as I am not completely sure if I want to have promises in the library or not. I'd rather let the user decide how to call the lsystem functions. We don't really do any per-se asynchronous tasks (like connections within a network, devices). Using promises would add more overhead and complexity withour adding any benefits at this point.
