null, only this flag and endian flag are set.
-- **endian flag** (bit 1): 1 when data is encoded by little endian, 0 for big
endian. Modern implementations always use little endian.
-- **xlang flag** (bit 2): 1 when serialization uses Fory xlang format, 0 when
serialization uses Fory language-native format.
-- **oob flag** (bit 3): 1 when out-of-band serialization is enabled

- **language**: 1 byte indicating the source language. This allows
deserializers to optimize for specific language characteristics.
