Add RandomOrder

[KumoLiu]

Part of #5517.

Description

When we have a list of transforms, we may want these transforms to do in random order. Add RandomOrder which is a subclass of Compose to provide the ability to apply a list of transformations in random order.

code looks good to me, I'm not sure about the class name RandomOrder, to me the operation is similar with np.random.shuffle https://numpy.org/doc/stable/reference/random/generated/numpy.random.shuffle.html

Yes, actually I'm referring to the name of torchvision.

Ok, that's also implemented with a 'shuffle'. Any particular reason that permutation is used in this implementation?

Yes, since self. transforms is tuple object, which does not support item assignment.

self.transforms = ensure_tuple(transforms)

Thanks!

Since the transforms are changed at every iteration, perhaps change it to a list and then shuffle the list is more efficient

Thanks, it looks good to me.
