💚 Fix IndexError due to Lake Whillans 6 disappearing

Since Subglacial Lake Whillans 6 'disappeared' in e5e91cd, shouldn't use it in the integration test. Oh yes, time to get back into this ICESat-2 project! Running things on a new workstation now and there's some exciting new libraries so best to wrap this up! Also gitignoring the dask-worker-space folder and some of the vector data files.
