Add flash support and updated benchmark.py and pyproject.toml

Context

- Edit the 'flash' directory to handle firmware flashing and UART output capture.

- Edit benchmark.py , add comput_output.

-Updated pyproject.toml to include pyocd and pyserial as dependencies for flashing support and add json fils in pip package

Modified files

• benchmark.py
• add flash folder
• pyproject.toml

Detailed major modifications

With these modifications, we now have a functional benchmark.py with a working compute_output function: running benchmark.py → retrieving inputs → compilation → creation of the benchmark_export_arm folder → retrieving the .elf file → flashing the board → collecting data → processing data → comparison.

I ran the test for the Relu operator.

TODO

• Add the measure_inference_time in the benchmark.py

• Test with another operator
