No help flag

[PaulRBerg]

I just installed scopelint for the first time, and I tried running this to get an overview of all available commands:

scopelint --help

I got this error:

error: Argument parsing failed with 'Unrecognized mode: Must be 'fmt', 'check', or '--version''

It would be helpful to provide a help flag.

Agreed. Working on a big refactor this/next week so things are cleaner and more scalable, part of that will include migrating to clap so we should get this as a result
