Allow looping when HIGH (#259)

**Allow looping when HIGH**

* Allow lflat glucose when CGM readings are HIGH (but disable SM and high temps) for IOB computations etc.
* Display HIGH when CGM reading is HIGH.
* Display real glucose when entering capillary glucose.
* Allow (capillary readings over HIGH for normal looping.
* Display in Enacted pop-up.
* Display warning in same pop-up
* Disable SMB and high temps in oref2 code when reading is HIGH (potential invalid CGM reading).
