Add MCCI driver installers

• Added MCCI driver installers (x64 & x86) and post_install.bat script for SAMD ([#45])

Add LoRaWAN network and subband UI

All user to use UI to inject information about the selected network and desire subband (if relevant).

Maintenance release

New features:

• Added support for the LoRaWAN Region KR-920 (#34 ).

• Rename AU921 region to AU915 (retaining CFG_au921 redundant symbol for older LMICs) (#37, #38).

• Add support for new IDE features for injecting precompiled objects (#39).

Add _mcci_arduino_version etc.

v2.0.0 makes a major version jump primarily to avoid reusing versions that are used by tags in the repo for Adafruit BSPs. It also adds _mcci_arduino_version (issue #28) to be consistent with other MCCI BSPs.

Fix version number in platform.txt

This release has a minor change that fixes version number in platform.txt.

Increase ring buffer size

This release increases the serial buffer size to 256 and can read 125 registers from a Modbus device(issue #26).

Bug fixes, small enhancements

This is a minor feature release. It moves flags in the link script to accomodate the BME680 BSEC library. It adapts the JSON templating system from the MCCI STM32 BSP. The millis() routine was updated so that the clock value will advance even if interrupts are disabled (issue #17). Properly define the country code for as923jp (issue #13). Fix typo: au915 in menus should have been au921 (issue #12).

Add Catena 4470 support, IDE LoRaWAN region control

v1.1.0 adds support for the MCCI Catena 4420 and 4470. It also adds the ability to select the target LoRaWAN region from the IDE Tools menu (assuming that you're using the MCCI Catena arduino-lmic library). It also fixes the USB product ID numbers to match the official numbers assigned by MCCI release engineering (issue #9).
