[develop-v3] Build error due to wrong library for ESP32

[EinfachArne]

Hey,

today I tried to compile the current development version of Homie-V3 via PlatformIO fpr an ESP32 and got the following error:

Compiling .pioenvs\lolin32\src\window_sensor.cpp.o
In file included from .piolibdeps/Homie/src/Homie.hpp:12:0,
from .piolibdeps/Homie/src/Homie.h:4,

My platformio.ini looks like that:

[env:lolin32]
platform = https://github.com/platformio/platform-espressif32.git#feature/stage
board = lolin32
framework = arduino
build_flags = -D PIO_FRAMEWORK_ARDUINO_LWIP2_LOW_MEMORY
monitor_speed = 115200
lib_deps = https://github.com/homieiot/homie-esp8266.git#develop-v3

The reason for that seems to be the use of a wrong library in scr/Homie/Boot/BootNormal.hpp. Instead of "ESP8266mdns.h" it needs to be "mdns.h" since only that is included in arduinoespressif32. After I changed it I was able to compile.

Have had the same issue. Your solution works also in Hamburg. Danke!

Sorry for that. Seems that I wasn't careful enough when merging the "disabling MDNS" commit from v2-#develop.
