Languages model extendet to cover usage in geodatenkatalog and perfomance increase for file type guessing.

I stumbled upon the debug logs of geodatenkatalog and decided to append the language codes used their to our language model. And while I had a minute in the train, I tried increasing the performance of our file type guessing for resources.

• Language codes extended using the three-letter identifiers from Wikipedia/ISO 639-2. Proper designations have been provided by an widely used AI tool
• Sorting the test to determine the file type in the order of their respective frequency increases performance as the test can stop once a format has been determined.
