本次Kornia 的更新中，主要增加对Canny的支持以及新增了多种图像处理容器（例如，视频容器，图像增广容器）。

例如对于数据增广中的各种常见格式（mask, bbox, keypoints），以及图像变换的inverse：

aug_list = AugmentationSequential(
    K.ColorJitter(0.1, 0.1, 0.1, 0.1, p=1.0),
    K.RandomAffine(360, [0.1, 0.1], [0.7, 1.2], [30., 50.], p=1.0),
    K.RandomPerspective(0.5, p=1.0),
    data_keys=["input", "bbox", "keypoints", "mask"],  # Just to define the future input here.
    return_transform=False,
    same_on_batch=False,
)
# forward the operation
out_tensors = aug_list(img_tensor, bbox, keypoints, mask)
# Inverse the operation
out_tensor_inv = aug_list.inverse(*out_tensor)

此外，我们新增了PatchAugmentSequential来支持更多最新的图像增强方法。
