Remove vendored dependencies

While it appears that by now we actually can get successful builds
without Cargo insisting on Internet access by virtue of using the
--frozen flag, maintaining vendored dependencies is somewhat of a pain
point. This state will also get worse with upcoming changes that replace
argparse in favor of structopt and pull in a slew of new dependencies by
doing so. Then there is also the repository structure aspect, which is
non-standard due to the way we vendor dependencies and a potential
source of confusion.
In order to fix these problems, this change removes all the vendored
dependencies we have.

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

-use rand_core::{RngCore, Error, impls};
-
-
-/// An RNG that reads random bytes straight from any type supporting
-/// [`std::io::Read`], for example files.
-///
-/// This will work best with an infinite reader, but that is not required.
-///
-/// This can be used with `/dev/urandom` on Unix but it is recommended to use
-/// [`OsRng`] instead.
-///
-/// # Panics
-///
-/// `ReadRng` uses [`std::io::Read::read_exact`], which retries on interrupts.
-/// All other errors from the underlying reader, including when it does not
-/// have enough data, will only be reported through [`try_fill_bytes`].
-/// The other [`RngCore`] methods will panic in case of an error.
-///
-/// # Example
-///
-/// ```
-/// use rand::Rng;
-/// use rand::rngs::adapter::ReadRng;
-///
-/// let data = vec![1, 2, 3, 4, 5, 6, 7, 8];
-/// let mut rng = ReadRng::new(&data[..]);
-/// println!("{:x}", rng.gen::<u32>());
-/// ```
-///
-/// [`OsRng`]: crate::rngs::OsRng
-/// [`try_fill_bytes`]: RngCore::try_fill_bytes
