Noyez zsh histdb import (#393)
* Attempting to implement zsh-histdb import
Import compiles passes tests, but doesn't run b/c of async runtime.
zsh-histdb uses sqlite, and sqlx-rs is async, but import code is sync.
* More working on importing histdb
* Rewriting tests and using `Vec<u8>` instead of `String`
- Rewriting tests to eliminate depencency on local file system
- Using `Vec<u8>` for command strings instead of `String` to eliminate
the utf8 errors i was seeing previously. Seems to be working.
* Running fmt
