* Add some improvements to the YOLO loss layer
Notably:
- stabilized bounding box regression loss during training by smoothing the gradient
- added the possibility to compute the iou_anchor_threshod adaptively with ATSS
(adaptive training sample selection)
- make use of the detection_confidence field in the truth box for class balanced loss
- added an optional gamma parameter to be able to use the focal loss in the classifier
* Added method to return a non-const reference to yolo_options
Also added the gamma_cls to loss_details operator<<
* Add focal gamma for objectness, too
* Fix yolo_options deserialization logic
* Remove non-const reference method to yolo_options
* use weight only for positive class, and be more consistent with floating types
* Use chrono in console progress indicator and add finish method
* Default print status to std::clog
* Print ellapsed time in parallel_for_verbose
* Fix typo
* Fix typo again
* Update release notes
* Fix spacing
* [TYPE_SAFE_UNION] removed explicit swap(). let the compiler define swap from move semantics
* - added type traits:
are_nothrow_move_construtible
are_nothrow_move_assignable
are_nothrow_copy_construtible
are_nothrow_copy_assignable
- everything has (conditional) noexcept specifiers
* - formatting
- bug fix
* - added .swap() back in
* - type traits
- added .swap(item) and swap(a,b) back in, but with some cleanup and all the noexcept
* added docs for swap(a,b) back in
