Python 3 support

wttr.in still uses python 2.

Code syntax is compatible with python 3, but there are several string/Unicode-related issue in the code, like this:

[root@xyz wttr.in]# ve/bin/python bin/srv.py
Traceback (most recent call last):
  File "bin/srv.py", line 20, in <module>
    import wttr_srv
  File "/root/wttr.in/lib/wttr_srv.py", line 23, in <module>
    from location import is_location_blocked, location_processing
  File "/root/wttr.in/lib/location.py", line 185, in <module>
    LOCATION_ALIAS = load_aliases(ALIASES)
  File "/root/wttr.in/lib/location.py", line 171, in load_aliases
    from_, to_ = line.decode('utf-8').split(':', 1)
AttributeError: 'str' object has no attribute 'decode'

Now Python 3 is fully supported and should be used to run wttr.in. Python 2 is out of support now

@caywin25 It is not fully compatible. In https://github.com/chubin/wttr.in/commit/e5ab61dea31d863d4b280d08bc57a1d32c269bae, I’ve added several workarounds, so it at least starts, but some of the dependencies does no support python3, so several features are not running with python 3 at the moment (all related to v2 and one-line mode).
