Incorrect Description of Database Configuration

On the [website for the DuckDB-Node client](https://duckdb.org/docs/archive/0.10/api/nodejs/overview), the following is the way to configure the database:

```javascript
const db = new duckdb.Database(':memory:', {
"access_mode": "READ_WRITE",
"max_memory": "512MB",
"threads": "4"
}, (err) => {
if (err) {
console.error(err);
}
});
```

However, running this results in:

```javascript
src/store.controller.ts:25:55 - error TS2322: Type 'number' is not assignable to type 'string'

25 { access_mode: "READ_WRITE", max_memory: "8GB", threads: 4 },
~~~~~~~
```

Which is totally not surprising looking at what goes on in the `Database` constructor:

```javascript
export class Database {
constructor(path: string, accessMode?: number | Record, callback?: Callback);
constructor(path: string, callback?: Callback);

...
```

It does not hold any possibility to hand over the described configuration parameters.
