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.

-# base32 [![Build Status](https://travis-ci.org/andreasots/base32.svg?branch=master)](https://travis-ci.org/andreasots/base32)
-
-This library lets you encode and decode in either [RFC4648 Base32](http://en.wikipedia.org/wiki/Base32#RFC_4648_Base32_alphabet) or in [Crockford Base32](http://en.wikipedia.org/wiki/Base32#Crockford.27s_Base32).
-
-# Usage
-
-```rust
-// crockford base32
-assert_eq!(encode(CrockfordBase32, [0xF8, 0x3E, 0x0F, 0x83, 0xE0]), Vec::from_slice("Z0Z0Z0Z0".to_ascii()));
-assert_eq!(decode(CrockfordBase32, "Z0Z0Z0Z0".to_ascii()).unwrap(), vec![0xF8, 0x3E, 0x0F, 0x83, 0xE0]);
-
-// rfc4648 base32
-assert_eq!(encode(RFC4648Base32, [0xF8, 0x3E, 0x7F, 0x83, 0xE7]), Vec::from_slice("7A7H7A7H".to_ascii()));
-assert_eq!(decode(RFC4648Base32, "7A7H7A7H".to_ascii()).unwrap(), vec![0xF8, 0x3E, 0x7F, 0x83, 0xE7]);
-
-// rfc4648 base32 without padding characters (=)
-assert_eq!(encode(UnpaddedRFC4648Base32, [0xF8, 0x3E, 0x7F, 0x83, 0xE7]), Vec::from_slice("7A7H7A7H".to_ascii()));
-assert_eq!(decode(UnpaddedRFC4648Base32, "7A7H7A7H".to_ascii()).unwrap(), vec![0xF8, 0x3E, 0x7F, 0x83, 0xE7]);
