 *
 * [[IRuntime]] implementations may use [[instance]]
 * to convert a batch of Collab messages into a single Uint8Array.
 *
 * As a common-case
 * optimization, this serializer applies suffix compression to
 * message stacks: shared (string) suffixes will only appear once
 * in the serialized message. That helps when stacks contain
 * Collab paths and there are multiple messages from Collabs in
 * similar parts of the Collab tree.
 *
 * This is a singleton class; use [[instance]]
 * instead of the constructor.
