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. Signed-off-by: deadprogram <ron@hybridgroup.com>
