nodestream - Storage-agnostic streaming library for binary data transfers

This is beneficial because it can move the "tee to a file" work off of us perhaps, but more importantly, agnostically provides transfer to various cloud services. For now, can just use it for local filesystem.

Also need to consider how tasks produce output. If it is a program that takes an outputFile as params for example, do we need to create a readstream on that file as it is created to produce an outgoing stream of it?

Not sure if enhancement or feature, it is a bit of both - not entirely necessary for MVP - but very useful to have.
