Fixed Eqtide-Thermint coupling so the CPL model can work with Thermint.

[RoryBarnes]

Added clean exit if user tries to select CTL model with Thermint.

Added unit tests for the CPL model with Radheat and Thermint.

Proposed changes

Previously only the DB15 model, which should never be used, was coupled to ThermInt. This change adds CPL to that list.
