using types directly for python2/3 cross compatibility

This fixes #100

[anthraxx]

new problem uncovered with python3:

Traceback (most recent call last):
  File "/usr/lib/python3.5/site-packages/distorm3/sample.py", line 46, in <module>
    for (offset, size, instruction, hexdump) in iterable:
  File "/usr/lib/python3.5/site-packages/distorm3/__init__.py", line 549, in DecodeGenerator
    for index in xrange(used):
NameError: name 'xrange' is not defined

will add another commit for that

patch updated and tested with the sample file. works fine with python2 and python3 now, from my side I'm ready 😄

Thanks, I will review/test and update.

Actually it doesn't work well for Python 3.0 and older Pythons. I'm on it. Thanks anyway.

[anthraxx]

You removed the decode from the library this fails for python3 as it returns bytes object. Notice the b'' around the sample disaster file whenn printing as and her decodes

[gdabah]

Damn it, even among the various Python 3.x it works differently. Yeah I was afraid it will break existing Python 2.x code base. Maybe we should make it conditional upon version?

[anthraxx]

At least for python 2.7 that works but yes, I'm not sure about older then that. Condition like in setup.py could work of you are concerned. Thx for your time

Ok, I will think how to implement it. Thanks for your help. I will commit something in the next few hours, would appreciate if you will be able to take a look.
