√(noham)² ae5035c6a8 optimize DASH probing and segment download paths ...

- Switch bruteforce probes from GET to HEAD to avoid downloading
  full segment bodies (only the status code is needed)
- Cap bruteforce concurrency with a semaphore (default 100) instead of issuing one task per tick, and cancel leftover tasks on early exit
- Reuse a single aiohttp session / event loop for the manifest mode's AVC/HEVC/audio bruteforces to keep TCP connections alive
- Hoist the per-request segment headers into a module-level constant
- Use a set for the already-downloaded resume check in save_segments
- Replace read()-into-memory copies with shutil.copyfileobj in   merge_segments and decrypt
