v0.4.0rc3

What's new

Added 🎉

• Added DatasetsFormat format and LoadStreamingDataset step to datasets integration.
• SqliteDictFormat for datasets.
• Added pre_epoch() and post_epoch() callback methods to PyTorch TrainCallback.

Changed ⚠️

• LoadDataset step from datasets integration is now cacheable, using the DatasetsFormat format by default.
  But this only works with non-streaming datasets. For streaming datasets, you should use the LoadStreamingDataset step instead.

Fixed ✅

• Fixed bug where KeyboardInterrupt exceptions were not handled properly by steps and workspaces.
• WandbTrainCallback now will use part of the step's unique ID as the name for the W&B run by default, to make
  it easier to indentify which tango step corresponds to each run in W&B.
• WandbTrainCallback will save the entire TrainConfig object to the W&B config.
