SJCGQ11LM - expose device temperature

[Masterz69]

Inspired by previous experience with Hubitat Elevation Xiaomi custom drivers by Markus (oh-lalabs.com).

Some Xiaomi/Aqara devices reports device internal temperature as data['65281']['3']. Like here:

debug 2021-10-12 04:58:43: Received Zigbee message from 'wlk BathR1 A', type 'attributeReport', cluster 'genBasic', 
data '{"65281":{"1":3055,"10":0,"100":0,"3":25,"4":5032,"5":13,"6":[0,1],"8":518}}' from endpoint 1 with groupID 0

"3":25 - this is device temperature.

It is already utilized in

• fz.RTCGQ11LM_interval (motion&lum sensor RTCGQ11LM) &
• fz.xiaomi_contact_interval (door magnet sensor MCCGQ11LM).

As well as Aqara SJCGQ11LM reports internal temperature.

IMHO it can be useful in some cases.
Device reports surface temperature with some offset:

• it can be used for rough heating control or to detect - hot or cold water leak happened, f.e.

I hope my changes are correctly done.
