Py3: AttributeError: 'str' object has no attribute 'decode'

[bitsgalore]

This happens when running under Py 3.6:

Exception in thread Thread-3:
Traceback (most recent call last):
  File "c:\python36\lib\threading.py", line 916, in _bo
    self.run()
  File "c:\python36\lib\threading.py", line 864, in run
    self._target(*self._args, **self._kwargs)
  File "c:\python36\lib\site-packages\iromlab\cdworker.
r
    resultPrebatch = drivers.prebatch()
  File "c:\python36\lib\site-packages\iromlab\drivers.p
    logUTF8 = log.decode("utf-16le").encode("utf-8")
AttributeError: 'str' object has no attribute 'decode'

This happens b/c in Python 3 a str object is already decoded:

So solution is to make decoding conditional on Py version.

Fixed: https://github.com/KBNLresearch/iromlab/commit/24858a15ed0a17d8325b524d6be520e686848b71, works with Py 2.7 as well!
