Suggestion: Add note in HAIntegration.cpp

Suggestion: Add note in HAIntegration.cpp that HASwitch(uniqueid) must not contain spaces.

HASwitch led("led");  // unique identifier must not contain spaces

Nice catch! I'm open to a pull request to this effect.

While looking around at the arduino-home-assistant examples I notices that you can set the icon, I do a pull request for this issue, would you mind if I changed the default icon for the LED?

    led.setIcon("mdi:led-outline"); // optional

Oh that's a terrific addition, hell yes, thank you.
