- The bug is that TransposeConv does not support explicit padding
which is needed in order to combine it with a proceeding Pad op
- The fix is to exclude such combination

The root cause of this diff is precision errors caused by rounding
several times when performing a resize bilinear upscaling to more than
twice the initial size. This is solved by rewriting the algorithm to
perform nearest neighbour upscaling to the correct size and then
applying one larger average pool instead of several 2x2 pools. Avgpool
with padding is limited to kernel size 8x8, which constraints the
largest possible bilinear upscaling to 8 times the input size.

- This bug causes a regression in the use of unpack and split operators
- The bug is due to the read_shapes attribute being an absolute calculation
for slice and strided_slice, but a relative one for unpack and split
- The fix is to consistently treat the attribute as a shape relative to the
read_offset

Fixed by adjusting zero points for ops with int8 IFM and asymmetric weights
since the reference does not support asymmetric weights for int8 IFM and
ignores the zero points.

Change convert_pad optimiser to use op.ifm_shapes attribute in place of
the fickle op.ifm.shape (which in this case had changed due to the
optimised-out reshape)

Removed graph optimizations no longer needed that caused problems
with FullyConnected operators running on CPU being consumed by
elementwise operators in Vela.

Added support to map TABLE operator to LUT.
Limitations:
-Only supported for int8
-TABLE input must be constant
This also adds the support for TFLite legalisation of
Tanh/Sigmoid (int8/uint8).

Memory only operators such as Reshape, Squeeze and ExpandDims are
removed in the graph optimiser step.
- Added semantic check that memory only operators have same
quantisation parameters on ifm/ofm.
- Added support for the ExpandDims operator.
- Addition and cleanup of related unit tests.
- Removed TOSA from the generated SUPPORTED_OPS.md documentation.

This is mainly to add support for depthwise conv2d
with dephmultiplier = 1.
(But there are no testcases suited, all I have sourced
has depth_multiplier set to 2, which is not supported.)
-Added support for depthwise conv2d.
-Added support for removing Transpose of constant data
-Added support for removing reshape

Added basic TOSA support, enabling Vela to
read and compile a .tosa file corresponding to
CONV2D + Rescale + Clamp, and writing it to an
optimized .tflite file.
The optimized .tflite file, will in this case, hold
a commandstream where the Rescale and Clamp has been
fused into the CONV2D.
The optimized tflite file is not output from Vela.
-Added support to read .tosa file into Vela
internal structure.
- Added tosa_reader.py, tosa_mapper.py and
helper files stored under tosa/
- Support for this limited to ~10 ops
-Added reader_util.py for functions common
for TOSA and TFLite
-Added tosa_graph_optimiser.py
-Added support to fuse Rescale into convolution
-Modified handling for padding
-Added support to fuse Clamp to previous op
-Added graph_optimiser_util.py
-Moved functions common for TOSA/TFLite graph
optimization to this file.
-Renamed graph_optimiser.py to tflite_graph_optmiser.py
-Added separate tosa_supported_operators.py
-Added supported_operator_util.py
-For functions in common for TOSA/TFLite
