Make Daemon feature imply streaming feature (#376)

* Streaming/audio-backend feature compile time check

Forbids compilation of one non functional feature combination

Now, `cargo check --no-default-features --features streaming` (lacking
an audio backend) returns a compilation error instead of silently
producing a failing binary.

* Make Daemon feature imply streaming feature

Remove runtime error, favouring compile time verification
