If same weight tensor was used with different block configs,
errors would occur.
Fixed by always cloning weight tensors, using a global weight
compression cache and modifying the linear allocator to
detect multiple usage of same weight compression.

This commit fixes a bug where there would be an off-by-one error
in some cases for ResizeBilinear.
It is resolved by treating it the same way as an AvgPool in
regards to setting the zero point.

This commit fixes the failing assert by removing it
and instead placing unsupported ResizeBilinear
operators on the CPU.
It introduces a new graph optimisation function
which adds the necessary attributes as well as
new operator restrictions for ResizeBilinear.

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.

- Pack and reshape operators were manipulating tensors of
different equivalence IDs that refer to the same memory
area, causing issues with block dependency checking.
Ideally we'd use address overlap calculations for accuracy,
but this commit implements a generalised solution by
setting memory op IO tensors to use the same equivalence ID.

This patch adds support for the ResizeBilinear operator.
It is implemented using a 2x2 Nearest Neighbor upscale
followed by a 2x2 Average Pool.
Depending on the argument align_corners
the output is either of shape:
- (2 * M, 2 * N) when align_corners == True, or
- (2 * M - 1, 2 * N - 1) when align_corners == False
where (M, N) is the input shape.
The padding mode is SAME when align_corners == True
and VALID when align_corners == False.
The argument half_pixel_centers is out of scope and is
as of now ignored.
Note that only upscaling by a factor of 2 is supported.

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.
