[DyfanJones]

This PR adds the following features:

• paginate function based off ticket: #30
• re-export paws.common helper functions so that paws.common is not explicitly needed to be called

library(paws.storage)

svc <- s3(confg())

paginate(
    svc$list_objects_v2(Bucket = "made-up")
)

I believe we are at a good point. All paginate information is passed from json file to paws so that we can build paginate queries correctly instead of guessing them. Next step will be to add unit tests.
