 If you set `.allow_extras()` on the main `App`, you will not get an error. You can access the missing options using `remaining` (if you have subcommands, `app.remaining(true)` will get all remaining options, subcommands included).
 You can access a vector of pointers to the parsed options in the original order using `parse_order()`.
