Nordic file format support for ObsPy

GNU Lesser General Public License, Version 3
(https://www.gnu.org/copyleft/lesser.html)
.. note::
Pick time-residuals are handled in event.origins[0].arrivals, with
the arrival.pick_id linking the arrival (which contain calculated
information) with the pick.resource_id (where the pick contains only
physical measured information).
note::
Station-magnitude residuals (only for New Nordic files) are handled in
obspy.core.event.magnitude.StationMagnitude.mag_errors.uncertainty.
note::
When you read a Nordic file into Obspy and then write to Nordic format, the
following information is not retained:
- amplitude-picks have no distance or azimuth to source
- some event (sub-)types may change if no equivalent event type exists in
Obspy
.. versionchanged:: 1.2.3
* The pick-weight from the Nordic file (0-4, 9) is now read into
pick.extra.nordic_pick_weight (was arrival.time_weight) while the
finalweight (0-100 %) is read into arrival.time_weight (or
backazmiuth_weight, respectively).
* Empty network codes are now read as None instead of "NA"
* Magnitudes are no longer automatically sorted by size.
.. versionchanged:: 1.2.0
The number of stations used to calculate the origin was previously
incorrectly stored in a comment. From version 1.2.0 this is now stored
in `origin.quality.used_station_count`
