Function sudo

sudo(
    session: SshSession,
    command: string,
    opts: SudoOptions,
): Promise<ExecResult>
Runs a command under sudo on an already-open session and collects its output.

Internally runs sudo -S -p '' <command>, writes password followed by a newline to the command's stdin (where -S makes sudo read it), sends EOF, then collects stdout/stderr and the exit code.

Caveats:
- the remote sudoers policy must allow password sudo and not require a tty (requiretty off - the default on most modern distros)
- command is interpreted by the remote login shell, so quote/escape it as you would on a shell command line
Parameters
- session: SshSession
  An open, authenticated SSH session.
- command: string
  The command to run under sudo (interpreted by the remote shell).
- opts: SudoOptions
  Sudo options; password is the user's sudo password.
Returns Promise<ExecResult>
The command's stdout, stderr, and exit code (0 on clean exit).
Throws
If the channel cannot be opened.

Throws
If the server rejects the exec request.

Since
1.0.2
Example
```
import { connect, sudo } from 'edgeport/ssh';

await using ssh = await connect({ hostname: 'h', username: 'u', password: env.PW });
const { stdout, code } = await sudo(ssh, 'systemctl restart myapp', { password: env.PW });
console.log(code, new TextDecoder().decode(stdout));
```
