CompatHelper: bump compat for Optim to 2

[MilesCranmerBot]

This is a clean rebase of #534 onto current master (minimal diff; no Manifest changes).

Change: allow Optim v2 in [compat].

Supersedes: #534.

[MilesCranmer]

@MilesCranmerBot I think you will need to update some of the code to work with the new Optim. See how this is done in DynamicExpressions.jl.

It would also be good if like DynamicExpressions.jl, we have a forced Optim v1 test to ensure AD-based constant optimization still works on older versions.
