Jack Grigg 93ee7143fe `impl From<&Assigned<F>> for Assigned<F>` 
In zcash/halo2#383 we altered the bounds on region assignment methods
like `Region::assign_advice` to constrain the value closure's result on
`for<'vr> Assigned<F>: From<&'vr VR>` instead of `VR: Into<Assigned<F>>`.
This had the unintended side-effect that `Assigned<F>` could no longer
be returned from the closure, because we were previously relying on the
implicit `impl From<T> for T` provided by Rust, which no longer fits the
bound. This commit adds the missing from-reference impl to restore
functionality, re-enabling inversion deferrment.
