Find or create a {@link CodecInteraction} to represent resetting the count
of a repeating group to the current index.

<p>For encoders, decoders, and codecs, this will be when the {@code resetCountToIndex}
method is called, e.g., {@code myGroup.resetCountToIndex()}.

<p>The supplied token must carry a {@link Signal#BEGIN_GROUP} signal.

@param token the token identifying the group
@return the {@link CodecInteraction} instance
