v4.0.0 Feature release, TYPO3 v12 support

New features 🚀

• TYPO3 v12.3+ support We added compatibility for TYPO3 v12.3+
• Added tagged headless data processors You can now for example use "headless-menu" instead FriendsOfTYPO3\Headless\DataProcessing\MenuProcessor in typoscript when defining data processors!
• PHP templates as an alternative to Fluid In this release, we are introducing a way to skip Fluid templates altogether when integrating external extensions! You can now prepare templates in pure PHP to handle JSON output without the need to deal with Fluid. Template path resolving is working the same as before. It makes templates so muuuuch simpler and easier to write.

v4.0.0 release has breaking changes

We removed dead or not needed code or change signatures of some methods, please review changes if you XClass our code.
