v0.4 🙌 New Dataset

TSDB v0.4 comes with a new dataset Italy Air Quality (https://archive.ics.uci.edu/dataset/360/air+quality). And since this new version, for the included datasets that have multiple subsets (e.g. PhysioNet2012 and PhysioNet2019), we will return them as separate sets because users may only need one subset for their usage.
