Vela was not able to parse config file paths entered with forward
slashes. This patch will make it possible to use both forward and
backslashes when specifying paths.

One level deep relative paths (ie ./vela.ini) were treated as the name of a
folder in config_files was ".". They are now treated as relative paths.
The warning message when using an absolute path has also been moved to
to the error message instead for a better user experience.

The argument to the lstrip function is a list of all characters that
should be stripped from the beginning of the string, in any order. To
remove the actual prefix, check if the string starts with the string
instead and then remove that amount of characters. The function
"removeprefix" was added in python3.9 which does exactly this, but
that is not yet available to vela since it supports python 3.7.

- For allocations that have a hard memory limit the Hill Climb allocator
should be given more attempts to find a solution that would fit
- The fix is to use a memory limit when there is a hard constraint, and
a minimum iteration count, reset on every improvement, when there is a soft
constraint
- Added maximum number iterations CLI option

- Added support for the ExpandDims operator.
- Addition and cleanup of related unit tests.
- Removed TOSA from the generated SUPPORTED_OPS.md documentation.

This commit adds a CLI option for setting
the recursion limit. This option was originally
removed because it was considered unnecessary,
but in some cases of very large (enormous) networks,
a RecursionError is encountered during graph traversal.
A simple solution for issues like those is to manually
increase the recursion limit.

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

Previously the debug database lost some operators in the debug database outputs when multiple custom operators were generated by Vela.
Also, the file offsets for command streams were always 0, even for a single custom operator. This patch should rectify these problems.
