Incompatible with pint unit registry configured with force_ndarray_like=True

[sguidara-ventus]

Describe the bug
Querying station data fails when using a pint unit registry configured with force_ndarray_like=True.

To Reproduce
Running the following code raises an exception:

from datetime import datetime

import pint
from wetterdienst.provider.dwd.observation import (
    DwdObservationDataset,
    DwdObservationRequest,
    DwdObservationResolution,
)

ureg = pint.UnitRegistry(force_ndarray_like=True)
pint.set_application_registry(ureg)

request = DwdObservationRequest(
    parameter=DwdObservationDataset.WIND,
    resolution=DwdObservationResolution.HOURLY,
    start_date=datetime(2024, 1, 1, 0),
    end_date=datetime(2024, 1, 1, 3),
)
print(next(request.all().values.query()))

The exception is raised with traceback:

    print(next(request.all().values.query()))
          ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

    return wrap_df(ldf.collect())
                   ^^^^^^^^^^^^^
polars.exceptions.ComputeError: TypeError: argument 'val': iteration over a 0-d array

Running the same code with force_ndarray_like=False runs just fine.

Expected behavior
Allow the querying of station data with a pint unit registry configured with force_ndarray_like=True.

Desktop (please complete the following information):

• OS: Linux
• Python-Version 3.11
• polars version 0.19.19
• wetterdienst version 0.71.0
• pint version 0.22

Additional context
I've had to use the configuration force_ndarray_like=True because it is currently required if I want to use pint-xarray (see xarray-contrib/pint-xarray#216).

I realize this bug is not necessarily the responsibility of wetterdienst, but perhaps there exists an easy change in this project that would fix this issue.
