… like the other unit tests (still generate fake images to avoid adding large files to the repo history)
…e directly from the NIH box share instead of from a mirror in a personal Google Drive

Summary
In preparation for the PyHealth 2.0 release, this PR cleans up a few loose ends in the
ChestXray14Datasetdataset.Changes
ChestXray14Datasetto download the labels and metadata CSV file directly from the NIH Box folder. When I originally implemented this dataset in ChestX-ray14 Dataset and Classification Tasks #392, I couldn't figure out how to download that file from Box automatically, so I mirrored it to my personal Google Drive. This PR fixes that.ChestXray14DatasetAPI docs.ChestXray14Datasetexamples from Jupyter notebooks to Python scripts. I also moved the examples toexamples/cxr/to avoid merge conflicts with Add/cxr comprehensive tutorial and benchmarks for PyHealth paper #773.ChestXray14Datasetunit tests to use thetest-resources/core/chestxray14directory instead of creating and deleting a temporarytestdirectory. This matches the pattern in the unit tests for other datasets. Test images are still generated at test time to avoid adding large files to the repo.PILdeprecation warning (Image.fromarray()will deprecate themodeparameter soon).Testing
