Prettify the counter example output

For slightly more complicated inputs it gets quite hard to read the counter example as it is displayed now.

Here is an example of a counterexample i just got:

[{"maxConcurrency":1,"queues":[{"concurrency":1,"kind":0}],"thingsToDo":[{"id":"2s","started":true,"fin
ished":false,"failed":true,"eventCount":1,"shouldFail":true},{"id":"!","started":true,"finished":true,"failed":false,"event
Count":0,"shouldFail":false}]}]

Even tho it is much more verbose, it is much more readable like this:

[
   {
      "maxConcurrency":1,
      "queues":[
         {
            "concurrency":1,
            "kind":0
         }
      ],
      "thingsToDo":[
         {
            "id":"2s",
            "started":true,
            "finished":false,
            "failed":true,
            "eventCount":1,
            "shouldFail":true
         },
         {
            "id":"!",
            "started":true,
            "finished":true,
            "failed":false,
            "eventCount":0,
            "shouldFail":false
         }
      ]
   }
]

I would find it very convenient to have an option to prettify the counter example to make it more readable when the input gets complicated.

Good idea, but probably not for the core package fast-check. I think we should be able to create a package @fast-check/prettier exporting a reporter and asyncReporter backed by prettier and doing what you asked for 🤔

Anyway, the idea is good 👍
Not sure when it will come in the official repo, but I keep the issue opened for a future task for the repo.
