Add some RAKwireless WisBlock based devices

I added some basic RAKwireless devices. Please check if we are doing it right.
About the "profiles", these devices are using LoRaMAC stack V1.0.2. I chose a naming that allows to define more profiles for LoRaMAC stack V1.0.3 and V1.0.4 that we will add later.

Thanks 👍 I have added a few comments.

@brocaar
Changed the file names and removed the ^

@beegee-tokyo the test is failing:

Sensor type error!: 66

Could you please check (make sure that the input bytes are integers, not hex).

@brocaar
Can you try again

(I deleted my prev. comment).

Could you update the common-names to match the Regional Parameters values? Sorry I have missed this in my review:

(AS923_1 -> AS923, AS923_2 -> AS923-2, ...)

@brocaar
Done.

Thanks @beegee-tokyo for adding the first real device :-) All tests are passing and I have merged your PR.
