Support for typo3/cms-composer-installers v4

Since TYPO3 v11, the plugin is not working anymore (even with composer-installers v3). Furthermore, in upcoming versions of TYPO3, the extension dirs won't have the typical structure typo3conf/ext or typo3/sysext. Most of my projects are already v11, in some of them I'm already using the v4-RC of typo3/cms-composer-installers. We really miss the comfort of this plugin! Let me know if there are any plans for updates - or if you need a sponsor.

Cheers
