13. def extractId(inputStream: InputStream, endianness: ByteOrder): Either[Array[Byte], Long]

    Extracts the schema ID from the avro single-object encoded at the head of this input stream.

    Extracts the schema ID from the avro single-object encoded at the head of this input stream. The input stream will have 10 bytes consumed if the first two bytes correspond to the single object encoded header, or zero bytes consumed if the InputStream supports marking; if it doesn't, the first bytes (up to 2) will be consumed and returned in the Left part of the Either.
