Feature reuquest: Scan multiple directories

[oliverklee]

As a developer, while developing extensions, I often need to scan Classes/, Configuration/ and Tests/ (and maybe Resources), but not the complete directory, as I need to not scan vendor/ (or .Build/vendor/in my case) as those contains 3rd-party classes I have no influence over. I would like to scan multiple directory at once in order to save time, e.g., like this:

typo3scan scan -t 6 Classes/ Configuration/ Tests/

Currently, this command results in the following error message:

Too many arguments, expected arguments "command" "path".
