Query FDSN web service for station metadata.

the service (e.g. ``'https://geofon.gfz-potsdam.de'``).
:type site: str, optional
:param url:
URL template (default should work in 99% of cases).
:type url: str, optional
:param majorversion:
Major version of the service to query (always ``1`` at the time of
writing).
:type majorversion: int, optional

Network timeout in [s]. Global default timeout can be configured in
Pyrocko's configuration file under ``fdsn_timeout``.
:type timeout: float, optional

If ``True`` arguments are checked against self-description (WADL) of
the queried web service if available or FDSN specification.
:type check: bool, optional
:param selection:
If given, selection to be queried as a list of tuples
``(network, station, location, channel, tmin, tmax)``. Useful for
detailed queries.
:type selection: list of tuples, optional
:param parsed:
If ``True`` parse received content into

Parameters passed to the server (see `FDSN web services specification

On failure, :py:exc:`~pyrocko.util.DownloadError` or one of its
sub-types defined in the :py:mod:`~pyrocko.client.fdsn` module is
raised.
