thx! Looks good but the build test is failing. Not sure if its related to adding 3.14. Should probably be fixed elsewhere.

So what seems to have happened here is that with python 3.14 the default error message for list.index() has changed.

3.13
ValueError: 'bla' is not in list

3.14
ValueError: list.index(x): x not in list

The actual problem is that there is no specific error message from pyfar if a wrong unit is entered in group_delay_2d. I opened an issue for that: #854
