update rusttype to 0.9.2, but find it still relies on old crossbeam…

…-utils

    Specifically, we still rely on crossbeam-utils v0.7.2, which has a known vulnerability fixed in v0.8.7

    It does not seem worth putting more effort into this at this time for two reasons:

    * Using `rote` does not involve connecting to the internet.
    * The vulnerability only affects 32-bit targets according to crossbeam-rs/crossbeam#781 . I'm not running `rote` on any of those at the moment, anyway.

    If `rusttype` releases the fixed version to `crates.io` then running `cargo update` will fix it for me, so I plan to wait until some time after that is released to address this.
