2020-06-18MLBEDSW-1971: Verify ifm block size calculation against specificationDwight Lidman
This commit ensures the IFM block size calculation in architecture_features.py matches the specification by correctly setting the ifm upscaling factor based on the upscaling mode. This requires adding an attribute to the Tensor object which stores the upscaling mode for that specific tensor and making sure that information is correctly carried over to shared_buffer_allocation.py.

2020-06-18Add pre-commit support for sanity checksDiego Russo
Use pre-commit framework [1] to run black and flake8 before the commit. black and flake8 are managed by the pre-commit framework and they can be run manually by the user using `pre-commit run` command. Fix the code base with the help of black and flake8. Fix import statements according to PEP8 guidelines [1] Both tools have the following settings (specified in the pre-commit configuration file): * line length: 120 characters * directory to exclude: ethosu/vela/tflite/ and ethosu/vela/ethos_u55_regs Updated README.md on how to install pre-commit and how to run sanity checks. Pipenv files have been updated including new dependencies for pre-commit.
