Ability to set the source folder for Package

[derikwhittaker]

It would be very helpful to be able provide the source folder for node-lamba to pull from rather than '.'.

The use case is this
I am using Babble to down compile to node 6.4. Babble will put folder in a folder, called '.babble' (for example).
I then would like node-lambda to pull files from .babble to package.

@derikwhittaker There is an option called -D, --prebuiltDirectory [PREBUILT_DIRECTORY], which allows you to specify '.babble' (for example).
How about specifying with this option?
