ESP32 Support?

[SlothCroissant]

First off - GREAT work on this, it's been wildly helpful in some IoT projects I've been doing around the house! Using this is miles easier than manual POST requests.

I accidentally ordered some ESP32 boards instead of ESP8266, and have been able to get the project working on the platform. I simply had to remove this codeblock from Pushover.cpp (setInsecure() is not available on the ESP32 WifiClient.h, that I've found - I think #12 calls this out as well):

	if (_unsafe) {
		client.setInsecure();
	}

This results in a fully working Pushover client library for the ESP32 - simple as that (I think?)

Quick ask - is there anything else that would be a blocker on the ESP32 that I'm not thinking of? I'm admittedly fairly new at cpp and Arduino/ESP programming, so thought I'd ask here to see if I should be keeping anything in particular in consideration. Alternatively, maybe you can consider expanding support to ESP32 if it truly is this simple.

Thanks for all your work on this!
