  1. Add a bound check for sas7bcat_parse_value_labels. 

    `lbp1` will try to chase and read as many value labels as `label_count_capacity`, which may result in accessing memory locations pass the allocated region, especially for malformed data. This also results in Address sanitizer error on some inputs. Add a bounds check to avoid it.
