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 Rust library for random number generation.
-
-Rand provides utilities to generate random numbers, to convert them to useful
-types and distributions, and some randomness-related algorithms.
-
-The core random number generation traits of Rand live in the [rand_core](
-https://crates.io/crates/rand_core) crate but are also exposed here; RNG
-implementations should prefer to use `rand_core` while most other users should
-depend on `rand`.
-
-Documentation:
--   [The Rust Rand Book](https://rust-random.github.io/book)
--   [API reference (master)](https://rust-random.github.io/rand)
--   [API reference (docs.rs)](https://docs.rs/rand)

-
-## Usage
-
-Add this to your `Cargo.toml`:
-
-```toml
-[dependencies]
-rand = "0.7"
-```
-
-To get started using Rand, see [The Book](https://rust-random.github.io/book).
-
-
-## Versions
-
-Rand libs have inter-dependencies and make use of the
-[semver trick](https://github.com/dtolnay/semver-trick/) in order to make traits
-compatible across crate versions. (This is especially important for `RngCore`
-and `SeedableRng`.) A few crate releases are thus compatibility shims,
-depending on the *next* lib version (e.g. `rand_core` versions `0.2.2` and
-`0.3.1`). This means, for example, that `rand_core_0_4_0::SeedableRng` and
-`rand_core_0_3_0::SeedableRng` are distinct, incompatible traits, which can
-cause build errors. Usually, running `cargo update` is enough to fix any issues.
-
-The Rand lib is not yet stable, however we are careful to limit breaking changes
-and warn via deprecation wherever possible. Patch versions never introduce
-breaking changes. The following minor versions are supported:
-
--   Version 0.7 was released in June 2019, moving most non-uniform distributions
-    to an external crate, moving `from_entropy` to `SeedableRng`, and many small
-    changes and fixes.
--   Version 0.6 was released in November 2018, redesigning the `seq` module,
-    moving most PRNGs to external crates, and many small changes.
--   Version 0.5 was released in May 2018, as a major reorganisation
-    (introducing `RngCore` and `rand_core`, and deprecating `Rand` and the
-    previous distribution traits).
--   Version 0.4 was released in December 2017, but contained almost no breaking
-    changes from the 0.3 series.
-
-A detailed [changelog](CHANGELOG.md) is available.
-
-When upgrading to the next minor series (especially 0.4 → 0.5), we recommend
-reading the [Upgrade Guide](https://rust-random.github.io/book/update.html).
-
-### Rust version requirements
-
-Since version 0.7, Rand requires **Rustc version 1.32 or greater**.
-Rand 0.5 requires Rustc 1.22 or greater while versions
-0.4 and 0.3 (since approx. June 2017) require Rustc version 1.15 or
-greater. Subsets of the Rand code may work with older Rust versions, but this
-is not supported.
-
-Travis CI always has a build with a pinned version of Rustc matching the oldest
-supported Rust release. The current policy is that this can be updated in any
-Rand release if required, but the change must be noted in the changelog.
-
-## Crate Features
-
-Rand is built with these features enabled by default:
-
--   `std` enables functionality dependent on the `std` lib
--   `alloc` (implied by `std`) enables functionality requiring an allocator (when using this feature in `no_std`, Rand requires Rustc version 1.36 or greater)
--   `getrandom` (implied by `std`) is an optional dependency providing the code
-    behind `rngs::OsRng`
-
-Optionally, the following dependencies can be enabled:
-
--   `log` enables logging via the `log` crate
--   `stdweb` implies `getrandom/stdweb` to enable
-    `getrandom` support on `wasm32-unknown-unknown`
--   `wasm-bindgen` implies `getrandom/wasm-bindgen` to enable
-    `getrandom` support on `wasm32-unknown-unknown`
-
-Additionally, these features configure Rand:
-
--   `small_rng` enables inclusion of the `SmallRng` PRNG
--   `nightly` enables all experimental features
--   `simd_support` (experimental) enables sampling of SIMD values
-    (uniformly random SIMD integers and floats)
-
-Rand supports limited functionality in `no_std` mode (enabled via
-`default-features = false`). In this case, `OsRng` and `from_entropy` are
-unavailable (unless `getrandom` is enabled), large parts of `seq` are
-unavailable (unless `alloc` is enabled), and `thread_rng` and `random` are
-unavailable.
