Richard Newman 2614f498be Ergonomics improvements, including a kw macro. (#537) r=emily
* Add TypedValue::instant(micros).
* Add From<f64> for TypedValue.
* Add lookup_values_for_attribute to Conn.
* Add q_explain to Queryable.
* Expose an iterator over FindSpec's columns.
* Export edn from mentat crate. Export QueryExecutionResult.
* Implement Display for Variable and Element.
* Introduce a `kw` macro.

    This allows you to write:

    ```rust
    kw!(:foo/bar)
    ```

    instead of

    ```rust
    NamespacedKeyword::new("foo", "bar")
    ```

    … and it's more efficient, too.

Add `mentat::open`, eliminate use of `mentat_db` in some places.
