[Enhancement] Get the ASR65XX chip running without Arduino

[miathedev]

Is there any documentation to get things running without Arduino?

You can use the SDK together with PlatformIO: https://docs.platformio.org/en/latest/platforms/heltec-cubecell.html

I suppose it's also possible to write your own build scripts. The drivers in the SDK are written in standard C and C++, and I'm pretty sure you don't need to use the Arduino sugar if you don't want it.
