SIGWINCH is a signal send to the process when the host terminal is resized, note that it's only available on Unix platforms. Catching this signal allows us to dynamically adapt the number of columns at a very low cost compared to `dynamic_ncols`. Indeed, as this approach is signal based, there is no need to poll the terminal size on each iteration. Signed-off-by: Lucas CHOLLET <lucas.chollet@free.fr>

@casperdcl as you seemed interested here. I didn't use
TMonitoras it seems unrelated to me, people might want to resize their terminals without paying the monitoring cost. But, I'm happy to make the change if you want it.
