insert(): Remove `unwrap()`s

Use a new `yaqlite::Error` type. Remove the other error types and use
this main error type everywhere. For now, that seems simpler.

The real reason why I centralised on one error type is that I wanted a
single `Error::Sqlite` variant for both `rusqlite::Error` and
`SqliteError` errors. However, I wasn't sure if it's possible to do that
with `thiserror`, and I didn't want to bother having to write my own
`std::error::Error` impls.
