6.0.1

This release fixes several issues with PHP 8 (undefined array keys, strict typing) and a couple of other bugs:

• when records are dropped by the isEmpty property, this is now logged when debug mode is activated
• the trim property now strictly trims only strings. Other data types are left unchanged. Note that this change may affect your existing imports if you relied on on-the-fly casting (see https://docs.typo3.org/p/cobweb/external_import/6.0/en-us/Administration/Transformations/Index.html#trim).
