Ok I'm running into a bit of a challenge writing tests here... All I need to do is create packaged material to pass into a reactor facility. But, mock sims don't support packaging. Ok, it's not that hard to add packaging to mock sim source. But mock sim sources are agent:Source, not cycamore:Source, so they don't have packaging.

There's basically three ways I see

1. Add packaging to agent:Source and Mock Sim
2. Create a version of Mock Sim that can spin up cycamore archetypes (Source or Storage) as ancillary agents (i.e. what is currently limited to MockSim:AddSource MockSim:AddSink
3. Create a version of Mock Sim that can create more than one testing archetype (right now a Mock Sim is initialized with up to one agent spec
4. Just run a whole simulation

Because I'm testing of the keep_packaging parameter in ResBuf (cyclus#1778), do I need testing here?

This PR does require cyclus#1778 to be merged first

I think it's best to use the boolean quantities for defaults, assuming we can
