added function to get just the real component from the CKKSPlaintext

[IanQS]

Simple code to get back the values as a real vector instead of a complex vector that needs to be converted on the users end

Nice suggestion, I was converting the complex in python, but it's better to have a native solution! Thanks

[IanQS]

Should I just merge these changes in then? What's the protocol? Sorry, there's no documentation about contributing to the library, so I'm not sure (we should probably get on that)

[reneroliveira]

Actually, the best protocol is to merge into dev first, but since it's something more urgent to the conference, I think it's ok
