check_return: Calling "Scan" without checking return value

[subpop]

A covscan check found that scanner.Scan is not checked for a return value in main.

#   108|   							scanner := bufio.NewScanner(os.Stdin)
#   109|   							fmt.Print("Username: ")
#   110|-> 							_ = scanner.Scan()
#   111|   							username = strings.TrimSpace(scanner.Text())
#   112|   						}
