LabStack Hygrometer Module

Based this of JaredC01's LabStack blank module.https://github.com/JaredC01/LabStack Still a workin progress! After a suggestion by Jared, I'm planning to add a hole to thread a screw in the back, to hold the hygrometer in place via pressure. I added a hole for a circular hygrometer. Because hygrometer clips are not always exactly at the same angle, I set the clip holes in the model at an off angle. You use the holes to insert the hygrometer, then rotate it until the display is properly aligned. This also helps hold the hygrometer in better.
