[FEATURE] Handle less-files found in the AssetCollector

[Ceremony64]

Since this extension only handles files defined in TypoScript, less added with the viewhelper f:asset.css will not.

With my pull request #36 it will now also work with f:asset.css and every other less file added to the AssetCollector

P.S. tested with Typo3 v12.4.11
