Using spectral v0.22.1 I got deprecation warnings from numpy and Orange didn't add the spectroscopy package. I see that @markotoplak restricted v!=0.23 due to some bug on Windows but maybe that was fixed in the newest version, v0.23.1. For now I leave that condition but changed >=0.18 to >=0.22.3. This seems to solve the numpy deprecation issue.
