Ophyd device for QNW temperature controller #267

The PV name for the device is 8idi:QNWenv_1, 8idi:QNWenv_2 and 8idi:QNWenv_3. Tom Walsh at BCDA wrote the EPICS IOC for it. The screenshot shows the caqtdm screen at 8-ID-I.

The device is the cornerstone for remote operation at 8-ID-I during Covid and will continue to operate after APS-U.

This is three different instances of the same QNW temperature controller (not a 3-channel controller).

Let's make a working ophyd Device in this repo, then apstools can hoist this so it becomes available for any beam line. Similar to the hoist for Lakeshore controllers.

@prjemian Gilberto's new Ophyd definition of PVPositionSoftDone also works. It now waits for the temperature to reach the set value within the tolerance just like a motor (see screenshot attached). The wait can also be bypassed by using bps.abs_set.
