Failed to parse Column type: SimpleAggregateFunction(max, DateTime64(3, 'UTC'))

[utkarsh-sib]

When reading from a table with column type SimpleAggregateFunction(max, DateTime64(3, 'UTC')) the following code tries to split max, DateTime64(3, 'UTC') by ,. Which results in an array of length 3. With parts max, DateTime64(3, UTC').

	func getNestedType(chType string, wrapType string) (string, error) {
	prefixLen := len(wrapType) + 1
	suffixLen := 1
	if len(chType) > prefixLen+suffixLen {
	nested := strings.Split(chType[prefixLen:len(chType)-suffixLen], ",")
	if len(nested) == 2 {
	return strings.TrimSpace(nested[1]), nil
	}
	}
	return "", fmt.Errorf("column: invalid %s type (%s)", wrapType, chType)
	}

This function returns an error if the length of the splitted array is not equal to 2.
Please check.
Thanks.
