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. Bug: https://github.com/ArthurSonzogni/FTXUI/issues/55
