trySplit()
If this spliterator can be partitioned, returns a Spliterator
covering elements, that will, upon return from this method, not
be covered by this Spliterator.

characteristics, estimateSize, getComparator, getExactSizeIfKnown, hasCharacteristicsSpliterator.OfDouble trySplit()
SpliteratorIf this Spliterator is Spliterator.ORDERED, the returned Spliterator
must cover a strict prefix of the elements.
Unless this Spliterator covers an infinite number of elements,
repeated calls to trySplit() must eventually return null.
Upon non-null return:
estimateSize() before splitting,
must, after splitting, be greater than or equal to estimateSize()
for this and the returned Spliterator; andSUBSIZED, then estimateSize()
for this spliterator before splitting must be equal to the sum of
estimateSize() for this and the returned Spliterator after
splitting.This method may return null for any reason,
including emptiness, inability to split after traversal has
commenced, data structure constraints, and efficiency
considerations.
API Note:
An ideal trySplit method efficiently (without
traversal) divides its elements exactly in half, allowing
balanced parallel computation. Many departures from this ideal
remain highly effective; for example, only approximately
splitting an approximately balanced tree, or for a tree in
which leaf nodes may contain either one or two elements,
failing to further split these nodes. However, large
deviations in balance and/or overly inefficient trySplit mechanics typically result in poor parallel
performance.

Implementation Requirements:
The default implementation repeatedly invokes Spliterator.OfPrimitive.tryAdvance(T_CONS)
until it returns false. It should be overridden whenever
possible.

Implementation Requirements:
If the action is an instance of DoubleConsumer then it is
cast to DoubleConsumer and passed to
tryAdvance(java8.util.function.DoubleConsumer); otherwise
the action is adapted to an instance of DoubleConsumer, by
boxing the argument of DoubleConsumer, and then passed to
