A #GBytes that contains multiple values.
The array of boolean that shows whether the Nth value is valid or not. If the Nth is_valids is true, the Nth values is valid value. Otherwise the Nth value is null value.
true on success, false if there was an error.
Append multiple values at once. It's more efficient than multiple append and append_null calls.
This is more efficient than arrow.fixed_size_binary_array_builder.FixedSizeBinaryArrayBuilder.appendValues.
