Added forward compatibility with flysystem API v2 while maintaining V1 compatibility.

Notable changes for ScormDisk.php -

• $filesystem->createDir($path);

• $filesystem->createDirectory($path);

• $filesystem->putStream($path, $contents);

• $filesystem->writeStream($path, $contents);

Hi @CThomas87 , I noticed the issue from putStream() from flysystem API too. Thanks for the update!
