Linear Unmixing

[ambrosejcarr]

Based on #990

• Updates the branch to use the scaling behavior in Move preserve_float_range #1041
• Removes the for-loop behavior in inner function of the _unmix method that is in [RFC] Add affine transform #990

Opening a new PR so that @kevinyamauchi can take a look at the tests and make sure everything checks out without me force-pushing his branch.

Thanks, @ambrosejcarr! Looks good to me. I didn't review the parts that are touched by other PRs (e.g., the new clipping stuff).
