FlatBuffer schema for OtpRef - service identity.

Used for all services (ephemeral and durable). Durable service IDs (like log_id) are encoded in the key path, not in this value.

Example

# Encode
binary = OtpRef.to_binary(%{otp_name: "bedrock_sequencer", node: "node@host"})

# Decode
{:ok, %{otp_name: name, node: node}} = OtpRef.read(binary)

# Convert to/from Elixir tuple format
ref = OtpRef.to_tuple(binary)  # {:bedrock_sequencer, :"node@host"}
binary = OtpRef.from_tuple({:bedrock_sequencer, :"node@host"})
