Update nitrokey crate to 0.2.3

This change updates the nitrokey crate to version 0.2.3. This version
bumps the rand crate used to 0.6.1, which in turn requires an additional
set of dependencies.

-//! A wrapper around any Read to treat it as an RNG.

-use std::io::{self, Read};
-use std::mem;
-use Rng;
-
-/// An RNG that reads random bytes straight from a `Read`. This will
-/// work best with an infinite reader, but this is not required.
-///
-/// # Panics
-///
-/// It will panic if it there is insufficient data to fulfill a request.
-///
-/// # Example
-///
-/// ```rust
-/// use rand::{read, Rng};
-///
-/// let data = vec![1, 2, 3, 4, 5, 6, 7, 8];
-/// let mut rng = read::ReadRng::new(&data[..]);
-/// println!("{:x}", rng.gen::<u32>());
-/// ```
