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. Delete subrepo argparse/:argparse Delete subrepo base32/:base32 Delete subrepo cc/:cc Delete subrepo cfg-if/:cfg-if Delete subrepo getrandom/:getrandom Delete subrepo lazy-static/:lazy-static Delete subrepo libc/:libc Delete subrepo nitrokey-sys/:nitrokey-sys Delete subrepo nitrokey/:nitrokey Delete subrepo rand/:rand

-/// The standard RNG. The PRNG algorithm in `StdRng` is chosen to be efficient
-/// on the current platform, to be statistically strong and unpredictable
-/// (meaning a cryptographically secure PRNG).
-///
-/// The current algorithm used is the ChaCha block cipher with either 20 or 12
-/// rounds (see the `stdrng_*` feature flags, documented in the README).
-/// This may change as new evidence of cipher security and performance
-/// becomes available.
-///
-/// The algorithm is deterministic but should not be considered reproducible
-/// due to dependence on configuration and possible replacement in future
-/// library versions. For a secure reproducible generator, we recommend use of
-/// the [rand_chacha] crate directly.
