Adafruit Feather nRF52 Pro for Mynewt

[Kevin Townsend]

This took a lot longer to release than planned, but just wanted to share 
this for anyone interested: https://www.adafruit.com/product/3574

Just waiting for the iOS app we wrote to get approved and some 
documentation cleanup, and it will be available in the shop shortly, and 
I'll be happy to get back to poking at Mynewt again with some sample 
applications!
