Keep Rust library up-to-date on crates.io

https://crates.io/crates/thrift

The most recent crate listed is `0.0.4`, which corresponds to thrift `0.10.0` as far as I can tell.

Would be nice if the crate was up to date and matched the thrift version.  So, the current crate would be `0.11.0` and the upcoming crate would be `0.12.0`.

It will obviously be a problem if the crate version needs to get bumped to `0.11.1` when no such version of thrift exists.  But at least the MINOR versions match, and that seems preferable to mapping the seeming unrelated `0.0.4` to `0.10.0`.
