Adding EV values to the output json file

[GuysmoB]

Hi,

I'd like to add EV values to the output file, next to each strategy action. I’d also like to round numbers to reduce the file size.
I'm not very familiar with C++, so I was wondering if someone could help with this task.
If it works well, I’ll create a pull request if the idea is appreciated.

Something like this:

"strategy": {
  "actions": ["CALL", "FOLD"],
  "hands": {
    "4c3c": {
      "strategy": [0.019, 0.98],
      "ev": [-10.5, 13.0]
    },
    "4d3d": {
      "strategy": [0.0, 1.0],
      "ev": [-122.3, -100.0]
    }
  }
}

I think i must start with the PCfrSolver.cpp file.

Thanks in advance for any help :)
