> In some cases it can be useful to get the field names from metadata in the order fields
were written when the metadata was created (i.e. object was serialized for the first time).
For example, this can be used to recreate the object using builder preserving the consistent
field ordering, so that {{BinaryObject.equals()}} method works properly.
> Basically, we just need to replace {{HashMap}} with {{LinkedHashMap}} in the {{BinaryType}}
implementation.
