Use LSR to mix/match different adsorbate thermo libraries.

Suppose you have some adsorbates in a Pt library and some in a Ni library, would it be nice to be able to use both libraries ("corrected" to a unique metal via LSR)

Until this is done, I think the Ni library that we have, is unusable. The code will assume it's Pt and scale it accordingly.
