Bug Fix

Correct power regulator setting for RAKwireless RAK11300 module from LDO to DCDC

# 2.0.3 - 2021-07-22

• Add RAK11310 support
• make include files SX126x-Arduino.h and LoRaWan-Arduino.h work for all board variants

Improvements

• Add callbacks for LoRaWAN TX finished (both confirmed and unconfirmed)
• Add additional bandwidths for LoRa transmissions. Breaks Radio.TimeOnAir() for bandwidths other than BW 125, 250 and 500
• Fix minor problem in CF list handling for AS923-x regions
• Implement new regions AS923-2, AS923-3, AS923-4, RU864
• Test CF list to add additional channel on AS923 and RU864

Big update !BREAKS BACKWARD COMPATIBILITY!

• Add support for all LoRaWAN regions without recompilation of the code
• Add background handling of SX126x IRQ's for better performance
• Read WHAT'S NEW IN V2 to migrate your application to V2

!BREAKS BACKWARD COMPATIBILITY!

AS923 join fix

• Fix AS923 OTAA join problem (use only default channels for join)
• Fix some smaller issues in LoRaMac.cpp

Fix join bug when first OTAA join fails.

When OTAA join failed callback was called, following lmh_join() calls fail always

New feature, update examples

Add callback for OTAA join failure
