[Request] do work on folder instead of archive file

[golfandsurf]

I haven't figured it out if it can already do this:
I'd love to see this be able to work through a directory, which basically has the contents of an unpacked jar. This would help me streamline some automation i have planned around this tool.

Sounds like this would be a useful feature, I've been thinking about it to. Maybe also add the ability to remap a single class file, someone else was asking about this earlier as well. Something like this:

--in-jar:

• .jar - remapJarFile
• .class - remap individual class
• isDirectory() or endsWith("/") - remap directory, fully traverse

--out-jar:

• isDirectory() or endsWith("/") - create directory and output each class
• anything else - create jar
