Also disable `/weights` dir creation when evolving as no weights are saved and empty folder causes user expectations of weights.

* Add `--int8` argument

* parents[0] bug fix

* Fix order

Thank you for sharing nice open-source codes 👍

I applied to shuffle the order of all 4(or 9) images in mosaic augmentation

Currently, the order of images in mosaic augmentation is not completely random.
The remaining images except the first are randomly arranged. Apply shuffle all to increase the diversity of data composition.
