[Feature request] Command line arguments

**Is your feature request related to a problem? Please describe.**

Im frustrated when I'm trying to run my app with specific arguments and I have to change the code-runner.executorMap for that specific language each time.

**Describe the solution you'd like**

I would love a parameter to easily add command line arguments to run the code with. or the ability to create my own parameters. example:

`$arguments
`

```
"code-runner.arguments": {
-d 0 -m 1 etc.
}
```
