To use, import API symbols like so:
```js
import { WmsEndpoint, WfsEndpoint } from '@camptocamp/ogc-client';
```
Note: if you want to disable web worker usage, for example to solve issues with the `Referer` header on outgoing
requests, use:
```js
import { enableFallbackWithoutWorker } from '@camptocamp/ogc-client';
enableFallbackWithoutWorker()
```
All processing will be done on the main thread after this call, including HTTP requests.
