deadprogram 68d4991da1 ateccx08: inttial implementation for ATECCx08
This working implementation for the ATECCx08 family of cryptgraphic processors
has random number generation and other needed supporting functions.

It also includes a sample of how to connect it to the Go crypto/rand package.

More cryptographic functions await a future interation.
