Matthew Naylor b2eabf4a9f Add tracegen scripts inc. bugfix from @mwachs5
A step towards moving the tracegen scripts from rocket-chip to
groundtest.  I will raise an issue requesting that the scripts are now
removed from rocket-chip by someone with write access.

I have updated the README to account for the move.

This commit includes a bugfix from @mwachs5 (with slight mods by me)
relating to potential division by zero in toaxe.py.
