ByteStruct<K extends ByteField<NativeType>> extension type

ByteStruct is a TypedData with keyed/named access to fields. TypedData + [] Map operators returning int keyed view mixin keyed access for serialization map

Wrapper over extension type. see StructData view ByteData or ByteStruct subtypes as base type. sufficent for iterative access.
