feat: support passing reporter options from config

[jkowalleck]

I saw that the reporter allowed passing reporter options – since #423.
This PR originally also include a use case: c8 config.

{
  reporter: ['text'],
  reporterOptions: {
    text: { file: 'coverage.txt' },
  }
}

Here is another real world use case:

{
  "all": true,
  "reporter": ["text-summary", "clover", "html"],
  "reporterOptions": {
    "clover": {"file": "coverage.clover.xml"},
    "html": {"subdir": "coverage.html"}
  },
  "reports-dir": "./reports",
  "temp-directory": "./.c8.cache"
}

Unfortunately, the original feature forgot to implement the solution to the exact use case.
SO the actual feature was never accessible/working/existing.

Here is the solution: reporterOptions from the config are passed to reporters.

I do not have any idea how the CLI could look like to configure this. So I did not implement it and also did not update any docs.
CLI might be like c8 --reporter-option clover.file=coverage.clover.xml --reporter-option html.subdir=coverage.html. Or something else.
