Release 2.0.1

• Removed auto creation of .env file if it doesn't exist mainly for performance reason, but also because of the introduction of $envFilePath argument
• Replaced file_exists by is_file method to get better performance
• Add the possibility to set env file path as suggested with issue #2 with optional argument $envFilePath

 public static function get(
        bool $usePutEnv = false,
        string $envKey = self::ENV_KEY,
        string $debugKey = self::DEBUG_KEY,
        string $envFilePath = ''
)
