[feature] Add support for EAP MSCHAPv2 (Doesn't work with iOS/MacOS)

[User-26]

Hello! OpenWISP-RADIUS is an awesome project, but it lacks one crucial thing: Apple devices can't authenticate because they only work with MSCHAPv2. Could you add MSCHAPv2 support?

I guess we're talking about WPA2 Enterprise TTLS, which for now we only support PAP, and you're asking to support MSCHAPv2. We're open for pull requests or support to get this done but we are not actively working on it right now.
