LoRA WAN LMIC improvement

[hpsaturn]

• fixed conflicts and PRs merged from @roberbike
• removed LMIC library files
• missing implementation of this library (missing LoRaWANSetup(); ??)
• issue: build fail for axp20x.h missing (maybe we need check the previous bullet)

[roberbike]

Why do these warnings appear?

I have a different issue:

Compiling .pio/build/LORADEVKIT/lib2c4/batterylib/battery_oled.cpp.o
In file included from .pio/libdeps/LORADEVKIT/LMIC-node/src/LMIC-node.h:82,
                 from .pio/libdeps/LORADEVKIT/LMIC-node/src/LMIC-node.cpp:53:
.pio/libdeps/LORADEVKIT/LMIC-node/src/boards/bsf_ttgo_t_beam_v1.h:83:10: fatal error: axp20x.h: No such file or directory

****************************************************************
* Looking for axp20x.h dependency? Check our library registry!

but maybe is possible that is a duplicated header or include or definition, in your case. Do you have a different branch? or it happens with this branch? with LoRA_Wan_LMic_improv ?

[roberbike]

Yes, the same branch LoRA_Wan_LMic_improv.
The same issue for ttgo_lora32_v1.
You can define ttgo_t_beam.h that does not use axp20.h and run with t_beam v1
