Cannot correctly marshal field that contains word "partial"

[MojoML]

Description: I have a Struct with the following field and tags PartialDeliveryNumber uint `json:"partialDeliveryNumber" csv:"partial_delivery_number"`

I have a test that reads in some json data and uploads it to Redshift. In order to upload this data, the column names have to be extracted from the records with this function:

// columns are determined by csv tags on the model
func GetColumns[T Model](records []T) ([]string, error) {
    var b bytes.Buffer
    if err := gocsv.Marshal(records, &b); err != nil {
        return nil, fmt.Errorf("failed to marshal csv headers: %w", err)
    }
    sc := bufio.NewScanner(bytes.NewReader(b.Bytes()))
    sc.Scan()
    cols := sc.Text()
    return strings.Split(cols, ","), nil
}

Problem: As soon as the Struct Field is named "PartialDeliveryNumber", the csv tag is ignored and "PartialDeliveryNumber" is returned as the column name. If I name the struct as follows, no issues occur: PDN uint `json:"partialDeliveryNumber" csv:"partial_delivery_number"`

After some debugging we found that the issue probably relates to this line in the library: https://github.com/gocarina/gocsv/blob/b87c2d0e983ae4eea4ee48f33de22d51ddd22f03/reflect.go#L228
