Cannot import on Windows

[cHemingway]

Attempting to import the library, with Python 3.8.1, Windows 10, gets the following error.

>>> import cxxfilt
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Users\christopher.h\AppData\Local\Programs\Python\Python38-32\lib\site-packages\cxxfilt\__init__.py", line 39, in <module>
    libc = ctypes.CDLL(find_any_library('c'))
  File "C:\Users\christopher.h\AppData\Local\Programs\Python\Python38-32\lib\site-packages\cxxfilt\__init__.py", line 36, in find_any_library
    raise Error('Cannot find any of libraries: {}'.format(choices))
cxxfilt.Error: Cannot find any of libraries: ('c',)

Checking the ctypes documentation, line 33 is not valid on Windows, as:

On Windows, find_library() searches along the system search path, and returns the full pathname, but since there is no predefined naming scheme a call like find_library("c") will fail and return None.

Instead, it appears find_mscvrt() should be used on windows, especially as libc is only being used for free()

Looking more closely at this, it seems UnDecorateSymbolName should be used instead of __cxa_demangle() on Windows.

Yes, windows is not supported now. I'm not familiar with using Python in Windows so there are a few questions to answer:

1. Does UnDecorateSymbolName use the same mangling rules as libstdc++/libc++? If not, what would a user expect this library to do? (update: Should it demangle using libstdc++'s rules or using MSVC's rules?)
2. Need to set up a CI for windows.

The import time error will be solved by #9.
The error will be delayed to demangle demangleb calls.
Open another issue if actual windows support is needed.
