Description
Like PyArrow, pylance should also support using fsspec-compatible filesystems via passing a filesystem argument, which could be a PyArrow filesystem object or an fsspec subclass, to dataset functions https://github.com/lance-format/lance/blob/4b9c7c17bd1a2fcdc611db2fef210ebb7d73ec4b/python/python/lance/__init__.py#L81 and https://github.com/lance-format/lance/blob/4b9c7c17bd1a2fcdc611db2fef210ebb7d73ec4b/python/python/lance/dataset.py#L5110.

Research direction
Start by reading python/python/lance/init.py around line 81 and python/python/lance/dataset.py around line 5110 to trace the dataset open and write entry points. Determine how a filesystem argument should accept PyArrow filesystem objects and fsspec subclasses, then verify that both dataset functions support those inputs.
