To achieve this, we make the following change when sideloading: Instead
of serializing associations and discarding duplicate *hashes*, we
memorize the *objects* (records) that we have already serialized, and
only serialize those that are new.
This change is mostly transparent, and brings down serialization time
from 3.1 seconds to 1.0 seconds on my set of sample data.
There is one change in the behavior: If you sideload the same object
multiple times, and it yields different hashes, like so:
embed :ids, include: true
has_many :comments
has_many :recent_comments, root: comments, serializer: CommentShortSerializer
then previously, it would be included multiple times, whereas now, the
first hash wins. (I haven't actually tested this.) I don't know that
either option is preferable. It's not covered by the test suite, and I
think it's an edge case that is OK to ignore entirely.
