Add corrections for coordinated omission

[ChillFish8]

As someone rightly pointed out the rust reddit, this does not accounting for coordinated omission so should probably be added.

I find the discussion about coordinated omission interesting as seen in https://github.com/giltene/wrk2, but I wasn't able to compile it due to luajit. I'll try to install this next.

@Zelnox If you're looking for something that does correct for coordinated omission then rewrk may not be for you as this is currently not implemented.
