Fix segment download merging on Linux machines

It seems on Windows the pathlib.iterdir() function is always in order. However, on Linux or at least some machines this is not the case. This change fixes the order.

If you think you were affected, check your previous downloads that used DASH or HLS segmentation and make sure they dont randomly change scenes out of order.
