Bump yaml-rust version

Closes rust-sailfish#38

`yaml-rust` and its dep `linked-hash-map` (with your PR merged) has been updated. This solves the immediate issue in rust-sailfish#38 but I'm still commited to creating a PR migrating from YAML to TOML when I get more time for it, see [my comment](rust-sailfish#41 (comment)) for why and when that will be.
