Hey,

while fixing #531, I thought maybe it would be nice if that were an own go package.

I built a similar thing in my cli (https://github.com/FriendsOfShopware/shopware-cli/blob/main/extension/util.go#L31) too. So I could reuse that code from there.

If you want, I can implement all that stuff with tests and move it to symfony-cli org repo? What do you think about this idea?
