ParseInt should use base 10 specifically, to avoid crashing on padded numbers

[Andrew Backer]

The default implementation uses base: 0 to autodetect the format based on the string itself. This fails for any zero padded integer greater than 7 :-/

 func toInt(in interface{}) (int64, error) { 
 	inValue := reflect.ValueOf(in) 
  
 	switch inValue.Kind() { 
 	case reflect.String: 
 		s := strings.TrimSpace(inValue.String()) 
 		if s == "" { 
 			return 0, nil 
 		} 
 		out := strings.SplitN(s, ".", 2) 
 		return strconv.ParseInt(out[0], 0, 64) 

While not strictly incorrect, this is parsing CSV data and not golang source code, and I'd be surpriced if there were 0x007 strings in a csv file that were expected to parse as hex, but base:0 supports it.
