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
  ) {
```
