If you receive a package with a data length of zero, parsePacket returns 0, but rx_buffer will exist. So if another parsePacket with no read access returns to zeros, there is still data that can be read. This example would not work: https://www.arduino.cc/en/Reference/EthernetUDPParsePacket
Also I added a check if rx_buffer exit when you try to flush it.
EEPROM.h uses data types which are declared through Arduino.h but that file does not contain an #include directive for Arduino.h. This does not cause any problems when the EEPROM library is #included from a .ino file because the Arduino IDE automatically adds an #include directive for Arduino.h but this is not the case for .cpp files. If a .cpp file has an #include directive for EEPROM.h that does not follow an #include directive for Arduino.h then compilation fails:

* Add `SYSTEM_EVENT_WIFI_READY` call back once wifi service is init. allows you to hook in, as the sdk does not generate this event for you.
As it stands the SDK does not appear to set `WIFI_MODE_NULL` correctly. if the wifi is initialised and set to `WIFI_MODE_NULL` it actually defaults to AP mode. This fix keeps `WIFI_MODE_NULL` within the ESP class if the wifi has not been init yet, and works in my testing. albeit a one sided conversation.

* make changes compatible with new _persistent behaviour.
wifi_err_reason_t doesn't have reason code 12. After reason code 11, we are getting wrong wifi disconnected reason message. Added "UNSPECIFIED" in place of reason code 12.
And above 201 reason code, it should be r-176 instead of r-177. Because messages are started from zeroth offset.
The wifi stack initialisation must be complete before calling `_udp_ota.parsePacket()` otherwise you just get a screen filled with
```
```
and due to the more async methods in ESP32 `handle()` may be called before this can occur.
If you develop on windows and need cr/lf files, see this:
https://git-scm.com/book/en/v2/Customizing-Git-Git-Configuration#_formatting_and_whitespace
Git can handle this by auto-converting CRLF line endings into LF
when you add a file to the index, and vice versa when it checks out
code onto your filesystem. You can turn on this functionality with
the core.autocrlf setting. If you're on a Windows machine, set it
to true - this converts LF endings into CRLF when you check out code:
$ git config --global core.autocrlf true

This code allows Wire.begin() to assign the default values of SDA, and SCL only if they have not been previously configured. Arduino libraries that use Wire() usually re-init the I2C interface in their initialization code with a call to Wire.begin(). If a user app sets custom pins assignment in setup(); These assignments will be overwritten with the default values whenever Wire.begin() is called.
