Minor miscellaneous fixes

See merge request !400

Create and use default Absolute class/module values, rather than hard-coding `shift` or `valid` values

- LegacySNCL's get_channel() now requires `data_type` argument
- For some reason, specifying a location code was intended to behave differently than specifying a `data_type` in SNCL.py. I can't imagine why, but I basically reverted a change made several years ago in commit 4fab9678 when I recently forced 'variation' and 'R?' to be treated the same way by SNCL.py.

There is an ambiguity that exists between `data_type` and `location` in *SNCL.py. Ideally, we'd clean this up, but that involves many changes, and well beyond just the *SNCL.py files. These changes at least fix issues with geomagio scripts that popped up during testing.

Handles case of broken IAGA2002 file where the channel headers don't align perfectly with the expected columns. Our IAGA2002 files never did this, but some from others did.

Clean up to support and/or match geomagio scripts

- `--ouput-scale-factor` for EdgeFactory and MiniSeedFactory
- `--ouput-sncl-mode` for EdgeFactory and MiniSeedFactory

- Remove unnecessary DED filtering; just copy to new sncls
- Trust *SNCL.py to map `HEZ` channel codes correctly (still uses `UVW` when applying calibrations to 10Hz volts and bins)
- Add `T5` to ObsRIO minute filtering

Update version metadata for new release

Copy F (geomag) to F (legacy) fixed:

See merge request !397

The EdgeFactory (earthworm client) does not have, and will probably never have, the ability to read floating point miniseed blocks. When we reverted the processing recently to stop making an integer copy of the 1-second data from ObsRio (which seriously confused Edge for reasons we still dont understand), this broke geomag-filter. The solution was to copy F data separately, using MiniSeedFactory as the input factory.

Do NOT "duplicate" raw 1-s data in EdgeCWB

See merge request !396

I mistakenly thought that only the float32 1-second data from ObsRIO systems was pushed to our ringserver, but apparently any/all LFF, LK1-4 channels are. This resulted in duplicate miniseed data going to IRIS, with one copy in the original float32 format, and another as scaled integers. This commit fixes this until/unless we can better reconfigure EdgeCWB to our needs.

Process default sncl_mode better:

See merge request !395

This was causing issues with the Controller, which always passes `sncl_mode`, even if it is None.

Add sncl_mode and scale_factor options to controller:

See merge request !394

I knew this in the previous commit, but I thought their parent class, TimeseriesFactory, could handle arbitrary keywords (i.e., it had a kwargs argument to vacuum up unrecognized keywords). I was mistaken.

These will be passed to IO factories if those factories accept them. As of this commit, only Edge and MiniSeed factories honor these options. Others should be updated to accept these, and apply them in a similar manner.

Added NEIC client parameters to FDSNFactory.py

Fix residual declination shift try2

See merge request !392

Added a default sampling period of Minute to the data.py file. This will allow users to leave sampling period blank in data endpoint.

Remove auto-shift, allow manual shift in calculate_D_absolute

See merge request !391

Turns out there are operational limitations that don't allow a
deterministic removal of the 180 degree ambiguity that exists
for calculated Declination. The one previously implemented only
worked for a subset of observatories. Now, we force all calculated
Declinations to point north(ish), which  is valid for most of the
globe, and all of the USGS observatories. However, if we ever
take absolute measurements in a location where the local magnetic
field points south(ish), we can simply provide a "shift" of +/-
180 degrees.
