data type in augmentation

[jizhang02]

Hello,

I'm curious whether the data type is limited to uint8, ranging from 0-255. In certain situations, such as medical imaging, the data type might be float32. Converting it to uint8 could result in a loss of information.

When I use import torchvision.transforms, it also only support uint8.

I think it's because transforms came from 2D images, where 0-255 range is typically used for RGB images. May be volumentations can be updated to work with float32.
