Create --help flag

[langston-barrett]

LSP doesn't support either --help or --usage flags. This is a barrier to usability. Suggestion: for good command line flags using Go, I've used this package.

Duplicate of #1, sorry. I'm happy to help with command line flag parsing, if you like.

That would have been amazing!

The cli options parser is at arguments.go. Reading unit tests at arguments_test.go also may be helpful. Feel free to substitute it with whatever external library you prefer. Thanks!
