Includes a number of changes:
* Handle non-existing optional inputs
* Handle disabled optional inputs (-1 indexed)
* Added unit tests for parsing operators
* Add bias tensor to the different Convolutions + FullyConnected if
it's missing.

add_input_tensor, set_output_tensor, create_const_tensor and
create_reshape_tensor have recently been added.
This replaces all found existing instances with these new helper
functions

The input tflite file potentially has metadata attached to it, which was
lost when writing the vela optimised tflite file out.
This patch preserves any metadata found.

- In networks that share the scale & bias tensor between operators,
differences in operator quantization causes conflicting HW packed
scale & bias values for the tensor. This commit replicates the
scale and bias tensors per operator, similar to weights handling,
to avoid this conflct.

Reshape ops should contain a "new_shape" attribute. An invalid tflite
file without this attribute caused vela to crash.
The new_shape however is the same as the output shape, so if missing, we
can easily add this missing attribute.

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 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.

- Removed the assert on datatype not being uint8/int8/int16
- Allow unquantised inputs
- This will break for float32 versions of supported operators

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.
