Update to the latest environment 0.0.7

I reinstalled IDE and latest Framework and Libraries but still does not work:

Now, the ESP32_LORAWAN library is not required, it is already included inside the new environment.

You can find OTTA in the 0.0.7 environment

I looked into the examples but did not find the OTAA example. Please describe how to get that.

Ok, i found that already. but that is different from that i used before. So that i need to change all my sketches i created before with older framework.
License is not need anymore from now?
Now:
Mcu.begin();
Before:
Mcu.init(SS,RST_LoRa,DIO0,DIO1,license);

We have built-in flash when we leave the factory
