option to remove problematic classes?

Given that the removal of problematic Java classes from files is trivial, it would very much improve this software if it added an option to do so.

```bash
zip -q -d $myfile org/apache/logging/log4j/core/net/JndiLookup.class
```
```bash
zip -q -d $myfile org/apache/logging/log4j/core/net/JndiManager.class
```
