Support babel compiled AST.

[ellioseven]

I use babel-plugin-graphql-tag to compile my queries, this is used mainly so I can use aliases when importing GraphQL files. However this doesn't work with the build tool as it appears fragments are not being imported.

It would be helpful to be able to crawl precompiled AST JS so that crawling can be done on resolved documents (prevent having to bootstrap babel).

For instance, something like:

# Build persisted queries across babel compiled GraphQL.
persist-grapqhl ./lib/grapqhl --ast --extension=js
