AWS docs indicate user data is base64 encoded, but tiny-ec2-bootstrap works without

https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/instancedata-add-user-data.html (and other places) indicate that AWS intends for user data to be base64 encoded, and will automatically encode it using the AWS CLI, etc.
If I encode (python boto3 in create_instances) user data in base64, it gets ignored. Works fine if I don't encode.
