Add a method that can get the reference class name, and add the parsing of generics based on the #getRefClasses method.

[kiteeel]

We require the fully qualified name on the classes referenced by a specific class. However, the CtClass#getRefClasses method appears to overlook the analysis of generic objects. To illustrate this issue, let us take the following classes as an example.
If we utilize the CtClass#getRefClasses method for the DemoB class, the returned collection solely comprises java.util.List.
However, with the incorporation of the latest CtClass#getAllRefClasses method, the returned collection comprises java.util.List and com.kite.DemoA.
Therefore, I kindly request you to consider and merge this pull request.

package com.kite;

import java.util.List;

public class DemoA {
    // ignored
}

interface DemoB{
    List<DemoA> getList();
}
