Change `composer.json` type to `wordpress-plugin`?

I'm not very good at the Composer stuff, but probably that's why I can't install the plugin properly now... Currently, if we require this plugin in a composer.json of a project, it gets installed into the vendor folder instead of wp-content/plugins. Maybe the type field in the composer.json should be changed to the custom type wordpress-plugin so we could define that it'd be installed into the appropriate plugin folder.
