write_sav: variable_display_width always 0

The Parameter for setting the display width is ignored:

import pandas as pd
import pyreadstat

df = pd.DataFrame({
    "v1": {
        "10001": """Lorem ipsum dolor sit amet, consectetur adipiscing elit. Maecenas ac pretium sem. Fusce aliquet
        augue rhoncus consequat pulvinar. In est ex, porta congue diam sed, laoreet suscipit purus. Phasellus mollis
        lobortis tellus at vehicula. Etiam egestas augue id massa bibendum volutpat id et ipsum. Praesent ut lorem

        "10002": "fgsdghshsgh",
        "10003": "gsfdgsdg",
    },

})

pyreadstat.write_sav(df, "export.sav", variable_display_width={"v1": 100})

df, meta = pyreadstat.read_sav("export.sav")
print(meta.variable_display_width)
#{'v1': 0, 'v2': 0}

Thanks for the report. It is the length of the string, if it is less than 256 characters, then variable_display_width is written correctly. If 256 or more then you get 0.

This looks like coming from the C code (Readstat, so I'll file an issue over there on your behalf)

Issue in Readstat: WizardMac/ReadStat#210

Solved on dev, although the max width right now is 255 (should be much larger)

this is now fully solved!
