Allow connections from anothers hosts

[andreibastos]

Added 'fromHost' in ForwardingOptions to allow connections from another's hosts.

// example

await sshConnection.forward({
    fromHost: '0.0.0.0',
    fromPort: 5980,
    toPort: 554,
    toHost: '10.0.0.141',
  });
console.log('*:5980 -> 10.0.0.141:554');
