Features. Load schema from json-array

[cia1]

I have already loaded schema from a file. Now I want to run validator. For that I have to load schema from a file again.
It will be excelent:

/**
 * Class HKarlstrom\Middleware\OpenApiValidation.php
 * @param string|array $filename
*/
OpenApiValidation::__construct($filename, array $options = [])

So, I can write somthing like this:

$schema = json_decode(file_get_contents($fileName));
$validator = new OpenApiValidation($schema)
