What's Changed

Added

• to_json and from_json methods now also natively support (de)serialization to/from
  files and file-like objects

Changed

• Instead of requiring already read string representations of json files, .from_json
  now also supports file paths as argument and will read the file itself
• from_json now strictly expects the source as a positional argument
• to_json now accepts kwargs and passes them to json.dumps

Fixed

• Crash in simulate_experiment when calculating cumulative best values for
  batch_size>1
• Campaign.allow_* flags now properly take into account recommendation caching
• The campaign recommendation cache is now properly invalidated during context changes
