0.4.0

Major changes

• AutoAlbument core is rewritten. Now AutoAlbument uses PyTorch Lightning to search for the best augmentation policies.
• Some configuration parameters in search.yaml are changed to work with PyTorch Lightning. The new release contains a new command named autoalbument-migrate which automatically converts an old config file to the new format. If you try to call autoalbument-search with the old config file, you will get instructions on how to use autoalbument-migrate.
