New tool: composer unused

[kaystrobach]

Would be awesome to support composer unused

• https://packagist.org/packages/icanhazstring/composer-unused

It detects non used packages and creates a report of that knowledge

Data type	Value
Tool name	composer-unused
Composer	icanhazstring/composer-unused
Repository	https://github.com/composer-unused/composer-unused
Xml Output	NO
Cli return code	YES
Cli Output	YES

I look a little into it.

composer-unused in not intended to be run as a Composer vendor binary.
(Only as Phar or as a Composer plugin)

I will open an issue on composer-unused to fix that
