Support CSI u numpad keys

Browse Source 
Normally page-down is sent as \033[6~ but some terminals
send a CSI u encoding for the page-down on the numpad. See
https://codeberg.org/dnkl/foot#keypad for example.

Treat them as the underlying key; we could add a modifier if anyone
cares about the distinction.
