Add support for TemperHUM_V3.8

[telmich]

The latest shipment has an updated firmware:

(venv) [13:47] server102.place10:~/temper# python temper.py -l
Bus 001 Dev 001 1d6b:0002   xHCI Host Controller ['hidraw0', 'hidraw1']
Bus 001 Dev 002 046d:0825    
Bus 001 Dev 003 1b3f:2247   GENERAL WEBCAM 
Bus 001 Dev 004 1a86:e025    ['hidraw0', 'hidraw1']
Bus 002 Dev 001 1d6b:0003   xHCI Host Controller 
(venv) [13:47] server102.place10:~/temper# python temper.py --force 1a86:e025
Bus 001 Dev 004 1a86:e025 TEMPerHUM_V3.8 Error: Unknown firmware TEMPerHUM_V3.8: b'8020065a0c360000'

This looks exactly the same as the previous white temperhum devices

From what I can see the following patch could already be enough for parsing:

@@ -206,7 +208,7 @@ class USBRead(object):
       self._parse_bytes('internal temperature', 2, 100.0, bytes, info)
       return info
 
-    if info['firmware'][:12] in [ 'TEMPerX_V3.1', 'TEMPerX_V3.3' ]:
+    if info['firmware'][:12] in [ 'TEMPerX_V3.1', 'TEMPerX_V3.3', 'TEMPerHUM_V3'  ]:
       info['firmware'] = info['firmware'][:12]
       self._parse_bytes('internal temperature', 2, 100.0, bytes, info)
       self._parse_bytes('internal humidity', 4, 100.0, bytes, info)

We could alternatively also parse for the whole TEMPerHUM_V3.8 string.

As well as adding the valid id list:

    if vendorid == 0x1a86 and productid == 0xe025:
      return True

Adding those two makes temper.py work for me:

(venv) [13:55] server102.place10:~/temper# python temper.py
Bus 001 Dev 004 1a86:e025 TEMPerHUM_V3 15.82C 60.48F 29% - - -

Can you advise which format you'd like for parsing the Firmware ID? Full string (TEMPerHUM_V3.8) or
abbreviated string (TEMPerHUM_V3)? I'll then submit a MR.

@urwen There are many PRs and issues open - would you be open for somebody else to take over the project? I can fork it, but I have seen that there is another stale fork at https://github.com/ccwienk/temper/ and I'd prefer avoiding to create another fork.

@telmich thanks, I just ran into this new updated firmware this morning, and you patch seems to be working well.
I suggest you send a PR to the fork at https://github.com/ccwienk/temper/ because that fork has more recent activity.

@telmich We're still taking PRs and issues over on ccwienk/temper. No guaranteed turnaround time, but we do get around to handling them.

We also publish the PyPi package temper_py.

Edit: I started working with that repo after no response from original author here. Given that it has been a good long while, I'm going to actually start deviating where it makes sense to do so rather than keeping the difference to this repo minimal. I.e., rather than just accepting a device add here and there, I might make structural changes where it makes sense to do so.
