Dirty but functioning SO-filter. Missing pieces

• Fix all ugly solutions
• move code from notebook to flagging.py
• clean up notebook
• check if stations have all nans (found no function to do that in xarray)

check if stations have all nans (found no function to do that in xarray)

If I understand correctly you can do something like this

da.isnull().all()
