       The  bson_append_oid()  function  shall append a new element to bson of type BSON_TYPE_OID. oidMUST be a
       pointer to a bson_oid_t.

       • bson: A bson_t.

       • key: An ASCII C string containing the name of the field.

       • key_length: The length of key in bytes, or -1 to determine the length with strlen().

       • oid: A bson_oid_t.

       Returns true if the operation was applied successfully. The function will fail  if  appending  oid  grows
       bson larger than INT32_MAX.
