[BUG] Example does not compile with PlatformIO

[BorisBrock]

I just created a new project using the provided example code. This is my platformio.ini:

[env:lolin32]
platform = espressif32
board = lolin32
framework = arduino
lib_ldf_mode=deep

lib_deps =
  ayushsharma82/ESP-DASH @ ^4.0.2

When compiling the project, it all ends in sadness:

How can ESP-DASH be used from PlatformIO?

Seems to be also an issue with the ESP Async WebServer dependency. Please see #195. I think the selection of the dependencies should be mentioned in the documentation, so people new to this project know how to fix it. Best would be, if the recommended dependencies could be listed there as well
