create overloaded functions for send and broadcast for easy usage

void sendTXT(uint8_t num, uint8_t * payload, size_t length = 0);
        void sendTXT(uint8_t num, const uint8_t * payload, size_t length = 0);
        void sendTXT(uint8_t num, char * payload, size_t length = 0);
        void sendTXT(uint8_t num, const char * payload, size_t length = 0);
        void sendTXT(uint8_t num, String payload);

        void broadcastTXT(uint8_t * payload, size_t length = 0);
        void broadcastTXT(const uint8_t * payload, size_t length = 0);
        void broadcastTXT(char * payload, size_t length = 0);
        void broadcastTXT(const char * payload, size_t length = 0);
        void broadcastTXT(String payload);

        void sendBIN(uint8_t num, uint8_t * payload, size_t length);
        void sendBIN(uint8_t num, const uint8_t * payload, size_t length);

        void broadcastBIN(uint8_t * payload, size_t length);
        void broadcastBIN(const uint8_t * payload, size_t length);
