we have already had a typeless `get` API:
```rust
/// get a configuration option
pub fn get(&self, key: &str) -> Option<ScalarValue> {
self.options.get(key).cloned()
}
```
for users who don't know the type of the config.
For other `get` APIs (get_bool, get_u8, get_string), I prefer returning an
error when the types aren't matched.
