-For `config-get`, `promiser('config-get')` is the preferred form. For backward
-compatibility, `promiser('config-get', undefined)` and
-`promiser('config-get', {})` are also supported.

 The `promiser` object above implements the
 [Worker1 API](https://sqlite.org/wasm/doc/trunk/api-worker1.md#worker1-methods).
