Update Semtech LoRaMAC Node Package

RIOT supports LoRaWAN through a in the house stack [GNRC LoRaWAN] and through the [Semtech LoRaMAC] package. The later is stuck on version V4.4.1 which implements the LoRaWAN specification 1.0.2. Since then 1.1 and 1.0.4 have been releaced, including among others security updates.

RIOT current support for [Semtech LoRaMAC] package will be the starting point, updatting the package to version > V4.7.0. It can be decoupled into two stages:

- Bump [Semtech LoRaMAC] to support the LoRaWAN 1.0.4 specification - Add support for the LoRaWAN 1.1 specification - Explore and add support for FUOTA, a good starting point are Semtech Loramac examples:

 - https://github.com/Lora-net/LoRaMac-node/tree/master/src/apps/LoRaMac/fuota-test-01

- Add lib for [LoRaWAN App Clock Sync](https://lora-alliance.org/resource_hub/lorawan-application-layer-clock-synchronization-specification-v1-0-0/) - Add lib for LoRaWAN utilities (OTAA incremental procedure, Blind ADR ...) - Add driver for SX1302 - Add Semtech UDP Packet Forwarder (for SX1302) : requires mainly a JSON parser lib.

SenML, SAUL, MQTT Integrations

The IoT, previously known as WSN (wireless sensor network) still finds many use cases in sensors networks. These usecases share a common base: need to convey a value, information of when/where the value was taken, and what that value corresponds too. Standarizing the way this is done, and doing so in a simple exntensible fashion has been done through [SenML](). SenML is defined by a data model for measurements and simple metadata about measurements and devices. It has recently been integrated into RIOT with a simple example using [SAUL](https://api.riot-os.org/group__drivers__saul.html), RIOTs sensors and actuators abstraction layer.

Popular communication protocols used in IoT include MQTT and COAP, RIOT supports both of them offering often multiple implementations. What's missing is a module integrating SAUL, SenML and different IoT communication protocols in such a way that setting up a IoT sensing application in a standarized way.
