ensure disagg uses correct model

[chrisdicaprio]

Is there a way (using THS?) we can ensure that a disaggregation is performed using the correct logic trees and hazard config?

Benefits:

• less for the user to put into input file
• less error prone

May want a mode where we perform a disaggregation that is not tied to an existing model, though, currently all disaggs look up the existing hazard curve to find a target IMTL.

may require logic tree info in THS metadata on a particular model
