Camera MTE3 sensor temperature read back value does not update until "Acquire" start.

Running MTE3 on ubuntu 18.04.
Camera sensor RBV value does not change until I command "Acquire" image.

I looked at the driver. There is no explicit code to read the temperature. It appears to happen in a callback function that PICAM calls when it changes. I don't know when those callbacks are enabled and occur.

I noticed that the ADPICam's database template:
https://github.com/areaDetector/ADPICam/blob/master/PICamApp/Db/PICam.template
is not referencing ADBase.template.
Maybe that's why the Temperature PV is not handled?

ADBase.template is being explicitly loaded in st.cmd, rather than being included in PICam.template:

ADPICam/iocs/PICamIOC/iocBoot/iocPICam/st.cmd
