Syntax error in decoder.py

[timokoesters]

I can't use this library because of the following error:
In line 230 of decoder.py is a syntax error:
result: int = 0

It should be:
result = 0

I am using Python 3.5.5

Is there any plan for a 3.0.2 release to make this fix available? Am also blocked by it.
