CLT/IAT/Aux in the new sensor world (#1269) 

* hook up clt

* init test

* probably fix test

* aux temp

* relax checking

* more significant figures

* remove old aux temp

* hand generate

* claim RAM

* move to ccm

* subscribe

* info printing

* warnings

* raise high voltage failure threshold

* fix test
