> ByteKeyRangeTracker.getFractionConsumed() invokes range.estimateFractionForKey(position) at following location.
> https://github.com/apache/beam/blob/master/sdks/java/core/src/main/java/org/apache/beam/sdk/io/range/ByteKeyRangeTracker.java#L127
> This invocation fails for out of range positions.
> https://github.com/apache/beam/blob/master/sdks/java/core/src/main/java/org/apache/beam/sdk/io/range/ByteKeyRange.java#L170
> But ByteKeyRangeTracker may accept out of range positions at following location.
> https://github.com/apache/beam/blob/master/sdks/java/core/src/main/java/org/apache/beam/sdk/io/range/ByteKeyRangeTracker.java#L80
> We can fix this by updating ByteKeyRangeTracker.getFractionConsumed() to return 1.0 for positions that are larger than the stop position, similar to OffsetRangeTracker.
