API non functional on Windows 1903 update.

[cmmv91]

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.

Interesting. Native WebAuthn API fallback sounds like a reasonable approach. I'll see if I can somehow try that out...
