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.

-**Problem**: `rand_hc::Hc128Rng: rand_core::SeedableRng` (or other RNG)
-
-**Quick solution**: `cargo update`
-
-**Details**: This happens when multiple versions of the `rand_core` crate are in use. Check your `Cargo.lock` file for all versions of `rand_core`. Note that some versions (0.2.2 and 0.3.1) are compatibility shims and are not a problem by themselves.
