    For our use cases it is important to know whether a value of cell is empty or it is 0.
    The EMPTY_STRING error could be intercepted by the csv parser in order to generate Row
objects with null values instead of 0 using the Table API

> In order to parse CSV files using the new Table API that converts rows to Row objects
(that support null values), FiledParser implementations should support emptry strings setting
the parser state to ParseErrorState.EMPTY_STRING (for example FloatParser and DoubleParser
doesn't respect this constraint)
