Yank versions 0.1.0 to 0.2.16

As of Rust 1.36, those versions don't compile. This was fixed for 0.2.17 by #61. I think it would be useful to yank those versions for cargo update -Z minimal-versions builds (https://github.com/rust-lang/cargo/issues/5657).

For convenience, commands that can be used to yank all those versions.

cargo yank --vers 0.1.0
cargo yank --vers 0.1.1
cargo yank --vers 0.1.2
cargo yank --vers 0.1.3
cargo yank --vers 0.1.4
cargo yank --vers 0.2.0
cargo yank --vers 0.2.1
cargo yank --vers 0.2.2
cargo yank --vers 0.2.3
cargo yank --vers 0.2.4
cargo yank --vers 0.2.5
cargo yank --vers 0.2.6
cargo yank --vers 0.2.7
cargo yank --vers 0.2.8
cargo yank --vers 0.2.9
cargo yank --vers 0.2.10
cargo yank --vers 0.2.11
cargo yank --vers 0.2.12
cargo yank --vers 0.2.13
cargo yank --vers 0.2.14
cargo yank --vers 0.2.15
cargo yank --vers 0.2.16

Review the issue's listed cargo yank commands and the context around Rust 1.36, minimal-version builds, and the fix in #61. Done means versions 0.1.0 through 0.2.16 have been yanked while 0.2.17 remains available.
