Don't run aria2c under asyncio, further improve progress updates
I've removed asyncio usage as it's generally unnecessary. If you want to run aria2c under a thread, run it under a thread. In the case for devine, this would take another thread, and would be another thread layer deep. Pointless. Would affect speed. With this change I've been able to improve the aria2c progress capture code quite a bit.
