csi: implement private mode 2031 (dark/light mode detection)

Browse source 
* Recognize 'CSI ? 996 n', and respond with
  - 'CSI ? 997 ; 1 n' if the primary theme is active
  - 'CSI ? 997 ; 2 n' if the alternative theme is actice
* Implement private mode 2031, where changing the color
  theme (currently only possible via key bindings) causes the terminal
  to send the same CSI sequences as above.

In this context, foot's primary theme is considered dark, and the
alternative theme light (since the default theme is dark).
