Add ability to configure JsonDriver and ObjectDriver

[alshenetsky]

This is very handy feature when comparing diffs between snapshots with unicode symbols

Aha, looks like we're doing some duplication. 😂 #131

it wasn't intended to (I saw this pull request after I made mine), but my PR probably have fixed one of your issue as well (the match part shouldn't matter anymore, you need to put the option for printing now only, that option could be also provided via a callback function so the user can whatever they want and return it, then you can save it.) check it out : https://github.com/spatie/phpunit-snapshot-assertions/pull/138

eg:

    private ?\Closure $manualEncode;
    public function __construct(\Closure $manualEncode = null) {
        if($manualEncode){
            $this->manualEncode = $manualEncode;
        }
    }

    public function serialize($data): string
    {
        if (is_string($data)) {
            $data = json_decode($data);
        }

        if (is_resource($data)) {
            throw new CantBeSerialized('Resources can not be serialized to json');
        }

        if($this->manualEncode){
            return ($this->manualEncode)($data);
        }

        return json_encode($data, JSON_PRETTY_PRINT)."\n";
    }

Or maybe even better : (after I thought more about your case)

    private $jsonEncodeOption = JSON_PRETTY_PRINT;
    public function __construct($jsonEncodeOption = null) {
        if($jsonEncodeOption){
            $this->jsonEncodeOption = $jsonEncodeOption;
        }
    }

    public function serialize($data): string
    {
        if (is_string($data)) {
            $data = json_decode($data);
        }

        if (is_resource($data)) {
            throw new CantBeSerialized('Resources can not be serialized to json');
        }

        return json_encode($data, $this->jsonEncodeOption)."\n";
    }

Combined with my PR everything should be backwards compatible.
