TensorFlow Federated 0.34.0

Release 0.34.0

Major Features and Improvements

• Updated to use Bazel version 5.3.0.
• Updated the conventions used to specify the version of a Python dependency,
  see https://github.com/tensorflow/federated/blob/main/requirements.txt for
  more information.
• Updated the setup.py to explicitly fail to pip install in Python 3.10.
  This has always been failing at runtime, but now explicitly fails to install
  using pip.
• Refreshed loading_remote_data notebook content and added content for
  FederatedDataSource.
• Added a TFF type_signature attribute to objects of type MapReduceForm.
• Added a series of slides to the GitHub repo (so not part of the PIP package) which detail a technical
  deep dive into TFF.

Breaking Changes

• Bumped tf-privacy version to 0.8.4.
• Bumped tf-model-optimization version to 0.8.3.
• Removed initialize from MapReduceForm.
• SequenceType now automatically casts any StructWithPythonType that
  contains a list to a tuple for tf.data compatibility.
• Unified the model_fn and model parameters of
  tff.learning.algorithms.build_weighted_fed_avg.
• MapReduceForm now takes a type_signature argument in its constructor,
  and no longer takes an initialize argument.
• MapReduceForm no longer contains an initialize attribute.

Bug Fixes

• Relaxed overly strict type equivalence check to assignability in TFF-TF code
  generation.
