Python bindings TypeError in reparse method

[bdcht]

Summary

In method 'reparse' of the python bindings (cindex.py), a TypeError is raised when 'unsaved_files_array' is set from name/value arguments when using Python3.
(This is due to Python3 mess with bytes vs unicode str...)
The way this unsaved_files_array is set here is not consistent with similar code in other methods like 'from_source' or 'codeComplete'. This proposed fix just
replicates what is done in from_source/codeComplete to set this ctypes unsaved_files_array.

I am sorry but I am not the right reviewer for that. Sorry!
