What happens with pV during mode=ts when lattice is kept fixed?

[pmrv]

I'm running some NVT calculations and want to compare the Helmholz Free energy, $F(V,T)$, to some other calculations (those kind of restrain me to keeping V fixed for now). I'm assuming calphy returns $G(p(T), T)$ along the implicit $p(T)$ path due to the constrained volume. If I want to transform back I can get $pV$ at $T_0$ from report.yaml, but what about the other temperatures?

@pmrv I think we cannot actually separate it out at the moment. Likely the pv terms go in automatically. We have to think about it a bit on how to implement.

Bummer, but it's not quite critical right now. I mainly want to compare to a NVT reference, but I might just have to go ahead and calculate NpT there to compare to calphy.
