Add SIIM ACR Pneumothorax dataset

[anwai98]

This is a dataset for segmenting pneumothorax in chest x-rays.

In addition, this PR also adds the feature to download files from kaggle using the Kaggle API.

Hi @constantinpape

This is a nice spot to review a few new features:

• Downloads are now possible from Kaggle (some simple steps in the beginning to make the API work)
• In ImageCollectionDataset, it allows now to accept patch_shape as None, and load the entire image as it is.
• Added a new transformation function called ResizeInputs, which is the skimage.transform.resize operation to resize the inputs based on a desired patch shape.

Let me know if you spot something.

PS. The dataset is around 4GB, in case you want to test it out.

• Some minor things can be improved in the handling if None patch shape, but looks good overall.
• This logic should also be implemented for the SegmentationDataset. Otherwise there will be a disconnect in the functionality.
• Some changes to the resize transformation.

Thanks for the mentions!

Re: This logic should also be implemented for the SegmentationDataset. Otherwise there will be a disconnect in the functionality.

I was thinking of doing it in another relevant PR once this is merged, where segmentation dataset is used (ideally for a 3d case like ACDC). Would that work, or should I take care of this in this PR?

Yes, that works!
