What is the idea?

Create a new function that can take an existing conda.models.environment.Environment instance and extrapolate/transform it for a different target platform while preserving compatible specifications.

Why is this needed?

This functionality is necessary for supporting multiplatform lockfiles in conda environments.

What should happen?

1. Given a conda.models.environments.Environment object, extrapolate a set of packages to solve for on a different platform. Derive packages using a combination of techniques:
   • topographical sorting of packages
   • from history file
2. We need to limit the total number of solves, ideally only one per platform
