ESP32 API Changes

[Psycardis]

I know this is an old project, but it looks like a great alternative to expensive foxes.

It appears that the esp32 api has changed at some point, and so when I am attempting to compile, I'm getting a lot of errors related to the rtc settings:

~/Arduino/LoRaFox/LoRaFox.ino:860:11: error: 'rtc_clk_cpu_freq_set' was not declared in this scope
           rtc_clk_cpu_freq_set(CPU_FREQ_HIGH);

Is there an easy way for me to update the code? All the mentions to CPU scaling in the esp32 documentation are above my head.

I was able to get everything to compile by changing my esp32 board version to 1.0.4 and my radiolib version to 3.0.0 in the Arduino ide. No clue if this actually works on board though, I bought a V3 by accident which isn't in the list of boards. I'll update if I get it working (or at least uploaded) on the V3.

I'm inclined to believe that this fixes the API compatibility problems, though I haven't built it, and I want to comment so that people know I haven't entirely fallen off the edge of the world since I wrote this thing. I don't want to just merge the request, because I'd like to understand what's changed first. The main sketch seems to have been moved to main.cpp, which is not a huge concern but it means the diffs show the whole file as being changed and I'll need to go in and manually compare things to see what's actually different. Pretty much all of morse.h seems to show diffs as well, which may indicate some tool or another has gone in and converted tabs to spaces or some other inconsequential thing.

Anyway, I'll try to look it over in more detail pretty soon. Thanks for doing the work.
