[download] fix: block_in_place for stream reads to prevent tokio starvation ... 694d638fb9

AllowStdIo<AudioDecrypt<AudioFile>> blocks the tokio thread on every read call.
With multiple concurrent download workers introduced in 43dcf56, all tokio
worker threads could be simultaneously blocked waiting for CDN data, starving
librespot's internal CDN download tasks that also run on the same runtime —
causing "Deadline expired" timeouts and eventual RateLimitExhausted errors.

Fix by wrapping each read with tokio::task::block_in_place, which signals to the
runtime that the thread is about to block so other tasks can be scheduled
elsewhere.

The previous tokio::select! with cancel.changed() provided no real benefit:
AllowStdIo::poll_read never returns Poll::Pending, so the cancel branch was
never polled concurrently. Cancel is now checked via borrow() at chunk
boundaries, which is equivalent in practice.
