Reading SAV file from your repository does not work :( #47

Hi!

Seems the reading SAV file is the showstopper - did workaround mentioned somewhere:
used pyreadstat and imported dataframe with dataset.from_components(df)

Unfortunately I miss SPSS meta data goodies. BTW is it possible to somehow import pyreadstat META part?

What I get with:
import quantipy as qp
dataset = qp.DataSet("My dataset, wave 1")
dataset.read_spss('"D:/tmp/Example Data (A).sav"')

is an error (using PyCharm and Python 3.7 venv):

Traceback (most recent call last):
