gem5 stats.txt to json

This script takes a gem5 stats file, and converts it into json for easier parsing

How to run?

make venv
. venv/bin/activate
./stats2json <stats file> <output file>

Note: There's no input file checking

ToDo

• Work for multiple stats dumps per run
• Use arrays for some things? (cpu0, cpu1 as cpu[0], cpu[1]?)
• Simplify reading numbers from histograms?
