processingStateRaw property

Apple's processingState, exactly as sent — the authoritative value. Null when Apple sent none.

processingState is this package's reading of this field, not the other way round. Calling this one a fallback would be backwards, and backwards in a way that costs something: when the reading is ProcessingState.unknown this is not a second-best source, it is the whole of what is known — so a consumer who has internalised "raw is the fallback" reaches for it last in the one case where it is all there is.
