Bad command line error on mistyped compiler flags

[dankeyy]

❯ roc fmt ~/testing/cli_test.roc
error: Found argument '/home/dankey/testing/cli_test.roc' which wasn't expected, or isn't valid in this context

USAGE:
    roc [OPTIONS] [ROC_FILE] [-- <ARGS_FOR_APP>...] [SUBCOMMAND]

For more information try --help

Instead it should say the second argument is malformed

Or to go the extra mile, do a flag suggestion by similar words bank
I had an idea to not even exit on bad keyword, rather

error: Found unexpected flag `fmt`. Perhaps you meant `format`.

Proceed with command `roc format cli_test.roc` [Y/n]? _
    ...

💯 I've been wanting that functionality for a long time
