It can be used to give developers a better control on the loop. Users
can use it not to take full control of the thread, and poll FTXUI from
time to time as part of an external loop.

The ESC key generates sequences that are prefix of others. For instance:
- ESC => [27]
- F1 => [27, 79, 8]
As a result, we can't generate the ESC event when receiving [27],
because it might be the start of the [27, 79, 8] sequence (or not).
Application usually applies a timeout to help detecting the ESC key.
This patch introduce a timeout. It is set to 50ms.
