### Setup Config Menu with StaticCell and Mutex

Source: https://github.com/oyvindnetland/esp-embassy-config/blob/main/README.md

Demonstrates how to initialize a configuration menu system using static allocation for configuration entries and a mutex-protected configuration menu. This setup defines configuration parameters at compile time.

```cpp
// setup config menu
static ENTRIES: StaticCell<[ConfigEntry; 2]> = StaticCell::new();
static CONFIG_MENU: StaticCell<Mutex<CriticalSectionRawMutex, ConfigMenu>> = StaticCell::new();
let entries = ENTRIES.init([
    ConfigEntry::new("value", 16, "What is this value?", false),
    ConfigEntry::new("long_value", 32, "What is this other value?", true),
]);
let config_menu = CONFIG_MENU.init(Mutex::new(ConfigMenu::new(entries, encoded_key, aes)));
```
