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 cryptographically secure random number generator that uses the ChaCha
-algorithm.
-
-ChaCha is a stream cipher designed by Daniel J. Bernstein[^1], that we use
-as an RNG. It is an improved variant of the Salsa20 cipher family, which was
-selected as one of the "stream ciphers suitable for widespread adoption" by
-eSTREAM[^2].
-
-The RNGs provided by this crate are implemented via the fast stream ciphers of
-the [`c2-chacha`](https://crates.io/crates/c2-chacha) crate.

-## Crate Features
-
-`rand_chacha` is `no_std` compatible when disabling default features; the `std`
-feature can be explicitly required to re-enable `std` support. Using `std`
-allows detection of CPU features and thus better optimisation.
