Built OK, but hangs up

[hendersj]

Just cloned this repo and built it - when I run the command, the desk moves (I can change the sit/stand positions just fine), but on every execution, I get the error message:

thread 'tokio-runtime-worker' panicked at 'index out of bounds: the len is 1 but the index is 5', src/desk.rs:179:6
note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace

The backtrace results in:

[jhenderson@TheEarth debug]$ ./uplift sit
thread 'tokio-runtime-worker' panicked at 'index out of bounds: the len is 1 but the index is 5', src/desk.rs:179:6

note: Some details are omitted, run with `RUST_BACKTRACE=full` for a verbose backtrace.

I can run a full backtrace if that would be helpful.

I am building/running on openSUSE Tumbleweed, if that makes a difference.
