[FEATURE] Compatibility with TYPO3 11

[CDRO]

Hi there,

we are planning on using this package for a project and will probably work on some fixes for TYPO3 11 (and maybe 12), would you consider merging these changes and publicly release a v2.0.0?

We'd probably be refactoring some parts and breaking dependencies to older TYPO3 and PHP versions, which would make a major release necessary.

Thanks for your consideration!
