options first in pod constructor

I believe that options should be first in the constructor here
```ts
abstract class ChartwerkPod<T extends TimeSerie, O extends Options> {
 // ...

 constructor(
 // maybe it's not the best idea
 _d3: typeof d3,
 protected readonly el: HTMLElement,
 protected readonly series: T[] = [],
 _options: O
 ) {
```
