Benchmarking in STM32 board

[NLNK]

Dear Sir,
Can you please share the details to do bench marking in STM32 for sphincs_sha_shake code. We have tried to do that with stack_speed_measurements_stm32f4.py file. But, it is taking more time(nearly half day) to display the results. It could be helpful if you share the best method to do that.

If you want to be faster I would suggest to modify this list so it only contains a single parameter set (128f should be the fastest). In general remove all the 's' sets and you will experience a massive speedup with fewer results.

Lines 30 to 33 in 597dd9c

	parameter_set_list = ["128f", "128s", "192f", "192s", "256f", "256s", # SHA robust
	"128f", "128s", "192f", "192s", "256f", "256s", # SHA simple
	"128f", "128s", "192f", "192s", "256f", "256s", # SHAKE robust
	"128f", "128s", "192f", "192s", "256f", "256s"] # SHAKE simple

...

However, a full benchmark is always going to take hours on that chip.
Hope that helps.
