/**
 * @brief Provides a web server for ESPMegaPRO
 * 
 * This class provides a web server for ESPMegaPRO. It is used to configure the device and to update the firmware.
 * This class also allows to save the credentials to access the web server in the FRAM memory.
 * User can also add custom endpoints to the web server.
 * 
 * This class use FRAM address 301-400
