API non functional on Windows 1903 update.

On the windows 1903 update microsoft is limiting native access to fido devices, they are providing their own API for interaction, the links below might be useful:

- https://github.com/Yubico/libu2f-host/issues/130
- https://docs.microsoft.com/en-us/windows/security/identity-protection/hello-for-business/webauthnapis

Maybe u2f-api can communicate webauthnapis to solve the problem for windows users.
