Add a parameter to detect compile scope dependencies that are only used for testing

[cesarsotovalero]

At this moment, DepClean analyzes the project's bytecode located in target/classes and target/test-classes. It is desirable to have a parameter that allows to not analyze bytecode classes used for testing in the project. This way, the dependencies that are only used for testing will be considered unused.

This parameter is useful to detect dependencies that have a compile scope but are only used for testing. Hence, these dependencies should have a test scope.
