Parse json5 codes always thorw JsonException on set JSON_THROW_ON_ERROR

Detailed description

Lines 75 to 80 in 7b4e50c

	if (PHP_VERSION_ID >= 70000) {
	$result = \json_decode($source, $associative, $depth, $options);
	if (\json_last_error() === \JSON_ERROR_NONE) {
	return $result;
	}
	}

in the code L76, if php version > 7.0 and set option JSON_THROW_ON_ERROR.

always thorw JsonException and interrupt subsequent processing

I think should auto remove JSON_THROW_ON_ERROR option on php > 7.0 in:

if (PHP_VERSION_ID >= 70000) { 
	// auto remove JSON_THROW_ON_ERROR option before call json_decode()
	
}

Ah yes, I see what you're saying.

I think should auto remove JSON_THROW_ON_ERROR option on php > 7.0

My preference would be to do the opposite - always set JSON_THROW_ON_ERROR and wrap this code with a try...catch block - something like this perhaps:

        if (PHP_VERSION_ID >= 70000) {
            try {
                return \json_decode($source, $associative, $depth, $options | \JSON_THROW_ON_ERROR);
            } catch (\Throwable $t) {
                // Ignore any exceptions that occurred, as we'll attempt to parse it ourselves if standard JSON parsing fails
            }
        }

I have not tested this, but I think it should work? If you or anyone else would like to implement this change I'd gladly accept the PR :) I would only ask that the PR also include a regression test where JSON_THROW_ON_ERROR is explicitly set when calling this to ensure that this issue is indeed fixed.
