Unknown after_config callback requested: lambda (not found)

[rmontgomery429]

I've added the following to the Gemfile:

gem 'sfn-lambda', '~> 0.1.0'

and this to the .sfn:

callbacks do
  default ['lambda']
end

and when I try to sfn print or sfn validate I get the following error:

Unknown after_config callback requested: lambda (not found)

After some investigation into another callback gem https://github.com/sparkleformation/sfn-parameters I noticed one difference that wasn't documented here in this repo.

https://github.com/sparkleformation/sfn-parameters#enable Specifies a require ['sfn-parameters'] which stood out to me. So I tried adding require ['sfn-lambda'] in a similar fashion to the callbacks section in our .sfn and it appears to work now.

Fixed via #2. Thanks!
