Typed filter handles for [`SessionTree`].

The session's own fields sit under [`session`], and [`windows`] is the
relation that makes a question about a session's contents expressible.

## Example

```rust
use libtmux::query::Filterable as _;
use libtmux::{SessionTree, WindowTree};

let sessions = SessionTree::filter_fields();
let windows = WindowTree::filter_fields();

// The session's own fields sit beside the relation rather than behind it, so
// a question about the session and a question about what it contains compose.
let building = sessions
    .session
    .session_name
    .starts_with("build")
    .and(sessions.windows.any(windows.window.window_name.eq("editor")));
```

## Members

- `session` (attribute): The session's own fields, the same set [`Session`] filters on.
- `windows` (attribute): The windows under this session.
