Use Extensions to support direct file reading support like CSV.read(dataset("..."))

It'd be great to overload some common file reader methods like CSV.read, JSON.read, Parquet.read, etc., to support reading directly from a ::DataSet reference. Having just a handful of these would drastically simplify the use of DataSets

We can couple this with 1.9 and Weak Dependencies

This is a great idea, but I am a little bit concerned about pushing all these dependencies onto pre-1.9 users right now.
