Load directly from S3

It would be nice to port over the S3 support from https://github.com/ZJONSSON/parquetjs

Would you accept a PR for this?

Seems like unrelated concerns. I don't feel like a transform library should know about storage mechanisms.

If it isn't aware of the storage mechanism, it might need some kind of plugin system for random access reads instead.

I think what it needs is simply support for Readable, just like it has for Writable?
