Putting back future bcs seems to be needed for past

This is because I ran into this error:

Apparently the future package does not obey the "grep rule" and defines builtins and past module namespaces, see https://python-future.org/compatible_idioms.html

Locally pip installing future fixed the issue so I believe putting back the future depends will fix the above error.

Oof, my bad! Approving now if it's blocking your work.

I wonder if we can update those usages? I could follow up later with that.

@bjester n.p. at all on ricecooker side, but please push a 2.1.0-alpha2 to PyPI just in case studio develop and vue-refactor branches run into this.
