Merge #368

368: Add an alternative AHT20 driver r=eldruin a=anglerud

I wrote a new AHT20 driver and published a blog post about it. I created a new driver as the previous one took ownership of the delay device, denying it to other drivers and code. The existing AHT20 driver is also under the AGLP which is certainly a fine license, but not one I'd choose for a library myself.
