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 macro for declaring lazily evaluated statics in Rust.
-
-Using this macro, it is possible to have `static`s that require code to be
-executed at runtime in order to be initialized.
-This includes anything requiring heap allocations, like vectors or hash maps,
-as well as anything that requires non-const function calls to be computed.

-## Minimum supported `rustc`
-
-`1.27.2+`
-
-This version is explicitly tested in CI and may only be bumped in new minor versions. Any changes to the supported minimum version will be called out in the release notes.
-
-
-# Getting Started
-
-[lazy-static.rs is available on crates.io](https://crates.io/crates/lazy_static).
-It is recommended to look there for the newest released version, as well as links to the newest builds of the docs.
-
-At the point of the last update of this README, the latest published version could be used like this:
-
-Add the following dependency to your Cargo manifest...
-
-```toml
-[dependencies]
-lazy_static = "1.4.0"
-```
-
-...and see the [docs](https://docs.rs/lazy_static) for how to use it.
-
-# Example
-
-```rust
-#[macro_use]
-extern crate lazy_static;
-
-use std::collections::HashMap;
-
-lazy_static! {
-    static ref HASHMAP: HashMap<u32, &'static str> = {
-        let mut m = HashMap::new();
-        m.insert(0, "foo");
-        m.insert(1, "bar");
-        m.insert(2, "baz");
-        m
-    };
-}
-
-fn main() {
-    // First access to `HASHMAP` initializes it
-    println!("The entry for `0` is \"{}\".", HASHMAP.get(&0).unwrap());
-
-    // Any further access to `HASHMAP` just returns the computed value
-    println!("The entry for `1` is \"{}\".", HASHMAP.get(&1).unwrap());
-}
-```
