Bump async dependency to 3.2.0 in atom/script

Update lockfileVersion to *2*, but that's a side affect from npm

https://github.com/caolan/async/blob/master/CHANGELOG.md#v200
v2.0.0 allows importing functions modularily.
So I changed the code to only import the functions needed
instead of the whole thing.
