V7 2629 support attributes

[Fl4m3Ph03n1x]

Background

This PR adds attribute import support for superannotate attributes.

How can I test?

Before testing there is one important detail: The attributes will only be imported if they already exist. Because for this condition to be true, the AnnotationClass must already exist and have the attributes defined, this means that if you are importing a new class, the class import will work, but it won't have any attributes.

A print message was added to give visibility to this issue.
