Add lifetime parameterization to async IPC reader

[sydduckworth]

Currently the async IPC reader (io::ipc::read::stream_async::AsyncStreamReader) has a 'static lifetime. It would be more ergonomic to parameterize its lifetime:

let mut buffer = futures::io::Cursor::new(Vec::new());
let reader = AsyncStreamReader::new(&mut buffer);
...
drop(reader);
let _out = reader.into_inner(); // This fails to compile because of the 'static mutable borrow
