What to do about a process still running where one is being respawned.

tmux refuses `respawn-pane` and `respawn-window` outright while the old
command is alive unless `-k` says otherwise, so the choice is not a detail
-- it decides whether a live process is killed.

## Example

```rust
use libtmux::Respawn;

// Rerun the pane's own command, killing it first if it is still running.
pane.respawn(None::<&str>, Respawn::Replacing).await?;
```

## Members

- `Replacing` (constant): Kill whatever is running first. tmux's `-k`.
- `OnlyIfDead` (constant): Refuse unless the pane or window is already dead.
