[FEAT] Make consumed PUs easily accessible

[SlowMo24]

What is the problem? Please describe.

To retrieve the processing units consumed by a request, one has to intercept the data retrieval and resolve the response headers before decoding the response manually like

    def _get_actual_pus(data: DownloadResponse) -> float:
        actual_pus = float(data.headers['x-processingunits-spent'])

Here's the solution

It would be nice to be able to just say e.g. data.pus.

Alternatives

Leave it as is, the interested person will find this solution
