fixes for 2023-11

[marcobrianza]

Just posting here some fixes that I needed to make to build the project in November 2023 with the current core

in esp32_pcap_serial.ino change this include #include "esp_private/wifi.h" //#include "esp_wifi_internal.h" esp32_pcap_serial.ino.txt

for SerialShark.py I used pyserial instead of serial and made the changes in the included file SerialShark.py.txt
