[feature] Add "SkipDependencies" argument to not save dependencies to disk

[NASGregorio]

I'm doing research on static analysis of decompiled code, and I'd like to only save the source files that exactly match the class filter.
Right now, when saving, using a filter for "com.foo" for example, the output folder will include the matching files plus dependencies ("com.google", etc)

Something like "setSkipDependencies" and "isSkipDependencies" would do the trick.
I already implemented this change, so if this is useful to others, I can make a PR.

The tool itself has been quite helpful so far. Thanks :)

@NASGregorio this will be very helpful 👍
Actually, this sounds like a bug, class filter intended to output only passed classes without dependencies.
Not sure if someone really needs dependencies after filtering, but having such option is nice anyway 🙂

If it is a bug, perhaps make excluding dependencies the default behaviour, and add the option "setIncludeDependencies".
I'll open a PR soon with the changes.
