fix(dependencies): fix lodash is missing bug

Unfortunately I assumed that lodash was a dependency already. In reality it was a dev dependency.
This meant that if you had your NODE_ENV set to production then you would experience this strange
but expected error. This fix moves lodash to be a full dependency.

Closes #61
