Add a 64-bit and 32-bit version for Windows.

After an upgrade easyhid stopped working.
I have tried to open a bug at hidapi site, but they say it's an easyhid issue.

Here's the problem:

Python 3.8.5 (default, Jul 21 2020, 10:48:26) 
[Clang 11.0.3 (clang-1103.0.32.62)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> from easyhid import Enumeration
>>> en=Enumeration()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.8/site-packages/easyhid/easyhid.py", line 366, in __init__
    self.device_list = _hid_enumerate(vid, pid)
  File "/usr/local/lib/python3.8/site-packages/easyhid/easyhid.py", line 428, in _hid_enumerate
    start = hidapi.hid_enumerate(vendor_id, product_id)
  File "/usr/local/lib/python3.8/site-packages/cffi/api.py", line 912, in __getattr__
    make_accessor(name)

    accessors[name](name)
  File "/usr/local/lib/python3.8/site-packages/cffi/api.py", line 838, in accessor_function
    value = backendlib.load_function(BType, name)
AttributeError: function/symbol 'hid_enumerate' not found in library '<None>': dlsym(RTLD_DEFAULT, hid_enumerate): symbol not found
>>> 

But if I type the following code, it works:

Python 3.8.5 (default, Jul 21 2020, 10:48:26) 
[Clang 11.0.3 (clang-1103.0.32.62)] on darwin

>>> import cffi
>>> ffi = cffi.FFI()
>>> hidapi = ffi.dlopen('hidapi')
>>> 
>>> from easyhid import Enumeration
>>> en=Enumeration()
>>> 

I'm using version: 0.0.10

pip3 show easyhid

What can I do ?

After installing easyhid with the special installing procedure.
I have tried to open a bug at hidapi site, but they say it's an easyhid issue.

What can I do?

I'm trying to get python easyhid.py to work under windows and it seems to require HIDAPI.DLL .. but the dll is not included. I have searched everywhere for this and I can't find a place to just download it. I see the hidapi project here https://github.com/signal11/hidapi , but not way to just get the DLL. Do I really have to get visual studio, install it, and learn how it even works, to build this DLL myself? can someone PLEASE help me and just tell me where I can download it? It would be extremely helpful. I have been looking for a simple way to obtain this DLL for days now. Trying to get this DLL to use easyhid is making it anything but easy.
