> RowCoderGenerator.encodeDelegate calls getValue for each field on a row
> twice, one to check if it is null in scanNullFields, and one to actually get
> the value to be encoded.
> If getValue is expensive (for example, it has to recursively adapt a type to
> a beam Row), this causes unneeded extra work.
> Instead we could call value.getValues to get all values once, then pass them
> to scanNullFields and re-use them when encoding the values.
