[BUG] using the exclude_empty filter doesnt filter out rows

[vincentkoppen]

Describe the bug
The VisionConverter with a yaml that uses the exclude_empty filter, doesn't filter out any rows.
Specifically if the column is a float column.

Currently the exclude_empty filter corrects for a pd.Series value of row[col] áfter it has called has_value.
However has_value doesnt work correctly for pd.Series, since it expects a standard python object.
