std::optional<char> GetKeyPrompt (std::string_view valid_keys, zx::duration timeout, std::string_view prompt)Given a collection of valid characters, a timeout, and an optional prompt string,
return the first valid key pressed before the timeout expired,

If the prompt string is not empty, it is printed once every second with a countdown
of the remaining timeout in seconds.
