Pyup.io's "safety" check failed on packages lxml, mako, and dparse.
None of these were explicit in our pyproject.toml file, but I modified
the entry to alembic, which was the package that required mako, then
ran poetry update to update the poetry.lock file.

To be honest, I'm not sure changing pyproject.toml file was needed
at all. I still don't fully understand how poetry works I guess. But,
everthing is "safe" now, and this merge request should now make it
through the CICD pipeline without further issue (fingers crossed).

The calculation of scale_value in geomagio.residual.calculate() is not
quite correct, but that needs to be addressed in a separate commit and
merge request. I'm reverting the recent change here so that we don't
break the tests.

Fixes #75

When geomagio.residual.calculate() is called with adjust_reference set equal
to True, the start/end timestamps now both reflect the time of the first absolute
measurement (i.e., West Down). This is consistent with the residual absolute
spreadsheet calculations.

update interval no longer shrinks with recursion

See merge request !186

Previously, the endtime-starttime interval being processed by the
`run_as_update` method would shrink by 1 (second) with each recursion.
This ultimately broke `run_as_update` when processing anything other
than 1-second data, but it wasn't obvious because we rarely had to
actually recurse. There is a little trickery now to ensure that user-
provided starttime and endtime are inclusive of the full first
(most recent) update interval, while subsequent, calculated, endtimes
are set equal to the prior starttime minus specified output_interval
(e.g., 'second', 'minute', etc.).

Gitlab 15 requires slightly different configuration to generate

Trying to dislodge a plugged pipeline in Gitlab

It turns out that none of the factories currently being used in
production expects bytes as input, and in fact, Util.read_url()
converts everthing to a string anyway, so a BYTES-oriented input
would couldn't not possibly be working. So, just remove all use
of BYTESIO, and instead use only STRINGIO.

It worked when a URL template was used, but not if a
single simple filename was passed

This is a bandaid to allow the `--input-url` option to be used to
read in single files. It adds zero functionality beyond what already
existed when the `--input-file` option was used.
