Is it able to specify the optimization level?

[Enter-tainer]

It's known that sometimes -O2 really makes your code runs faster. Whlie I'm solving some poisonous problems, I find that my code would get TLE without O2 optimization. So is it able to specify the optimization level in config.json?

{
  "Source"       : "example.cpp",
  "Input"        : "example#.in",
  "Output"       : "example#.ans",
  "#"            : [1, 2, 3, 4, 5, 6, 7, 8, 9, 10],
  "Time Limit"   : 1000,
  "Memory Limit" : 128,
  "Optimization Level" : "O2"
}

{
  "Source"       : "example.cpp",
  "Input"        : "example#.in",
  "Output"       : "example#.ans",
  "#"            : [1, 2, 3, 4, 5, 6, 7, 8, 9, 10],
  "Time Limit"   : 1000,
  "Memory Limit" : 128,
  "Optimization Level" : "O2"
}

或者在程序启动的参数中指定，例如：

$ rlj [-s|--slient] [-j Source | --judge Source] [-c ConfigFile] [-O2]

Yes, I have considered this, and I add Compile parameter in config.json（but I have forgot it）.

Since -O2 is used so often, I will consider add it to the argument.
