03: Replicate ls

This starts you off with a simple command line parsing library and a globbing library to get going named fast-glob. "Globbing" is what you're doing when you use regular expression patterns to match files like this:

ls *.txt

The fast-glob library is a good library with only one quirk to watch out for: It will not convert \ (backslash) characters to / in your glob. That means if you use C:\Users\zed\*.txt it will fail. You'll have to convert all \ to / on Windows.

File Attributes

Part of the ls command is printing out the attributes of a file. For that you'll need fs.stat found in the fs module.
