- 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

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.

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.

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

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

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.

- MiniSeedInputClient expects a stream as input, not a trace
  (like RawInputClient), and unit tests were designed around this;
  I reverted _put_channel() to its original design, which sends an
  entire stream instead of one trace at a time.
- I forgot to include a tiny change to RawInputClient_test that was
  part of the original (abandoned) MR
- I also made the read client timeout configurable

- assumes updates to filters.py, EdgeFactory, and MiniSeedFactory included in this feature branch
- removes default ports in favor of factory defaults
- tenhertz data will still use MiniSeedFactory, and if channels "U", "V", or "W" are requested, the raw voltage and bin data will be used to calculate nT outputs

- stop using factory.py; just instantiate factories in filters.py...it's only a little extra code, and a lot less confusing
- copy 1-second ObsRio float data (e.g., F, UK*) to RawInput so it is available using EdgeFactory, and also so we have the option in the future to prune 10Hz data from EdgeCWB that has already been archived at IRIS.
- set up calls to _copy_channel to legacy sncls to be removed once Edge data migration is complete
- make all *_filter methods require an instantiated io factory, and set no default options
- other than the *temporary* write ports for copies of legacy sncl data, allow no default ports in filters.py; either accept the factory defaults, or force user to specify ports with call to geomag-filter app.

- better handle hour and day intervals in create_empty_trace
- enode_stream now handles "STEIM" encoding
- fixed bug in pad_and_trim_trace

- align timestamps more consistently for "update" intervals
- (related) add "interval" option to get_realtime_interval

- handle intervals other than 1s and 1m properly

    - configurable scale_factor and float vs. int conversion logic
    - configurable sncl_mode for different channel mapping
    - multiple read ports allowed for fail-over logic
    - generally more (if not perfectly) compatible with MiniSeedFactory

Better mapping of publication level to imag or imf. Compression and Fill Value constants. Code simplified.
