Suggestion - Ignore classes that extend / implement

[xXkguyXx]

Which version of Radon are you using? (Do not say "latest", if you do, your issue will be immediately closed)
1.0.3

Have a suggestion here. Would be nice if you could add some sort of way to ignore classes that extend or implement another class. For example, if you add extends me.database.fruits.Fruit, or implements me.database.fruits.FruitInterface, it will be ignored if it extended/implemented in the class to be obfuscated.

Thanks ;D
