This release incorporates a number of new features from @disk91 to better support Arduino MKRWAN boards, fixes a couple of bugs, and bumps LoRaMAC-node to version 4.7.0.

New features
The new command AT$NVM can be used by the host MCU or application to store a limited amount of user data in the modem's flash. This can be useful for storing per-modem application configuration information in the modem.

The new command AT$LOCKKEYS can be used to prevent the application from reading LoRaWAN security keys over the AT command interface. Once invoked, the LoRaWAN security keys stored in the modem cannot be read until the next factory reset. Please note that this command provides accidental protection only. The security keys can still be accessed over the USART ports or by reading the EEPROM.

The new command AT$DETACH, which is only available in the build variants for Arduino MKRWAN boards, can be used to detach the LPUART1 port (the ATCI port) from its GPIO pins. This allows the host MCU to communicate with the onboard flash which shares communication lines with the LPUART1 port in the Murata modem. To re-attach the port, the host MCU pulls the GPIO pin PB12 down.

Improvements
This release also updates the LoRaMAC-node library to version 4.7.0. The update brings in the most recent bug fixes and minimizes the number of custom modifications we need to keep.

Bug fixes
This release also fixes incorrect handling of DevEUI during factory reset. In previous firmware versions, AT+FACNEW 3 did not correctly reset the DevEUI.
