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.

-Implements the Xorshift random number generator.
-
-The Xorshift[^1] algorithm is not suitable for cryptographic purposes
-but is very fast. If you do not know for sure that it fits your
-requirements, use a more secure one such as `StdRng` or `OsRng`.

-## Crate Features
-
-`rand_xorshift` is `no_std` compatible. It does not require any functionality
-outside of the `core` lib, thus there are no features to configure.
-
-The `serde1` feature includes implementations of `Serialize` and `Deserialize`
-for the included RNGs.
