Initial implementation of line matching (#182)

* rename and move function to return available line catalogs.

* tweak docstring; add initial sketch for LineMatch classes

* dev notebook work; more line_matching sketch-up

* add ruff config to pyproject for faster linting

* remove check for astropy < 3.x

* add missing function to __all__ in synth_data.py

* make the spatial profile for a traced source a passed argument vs hard-coding Moffat1D. need Gaussian1D for some test cases

* codestyle cleanups

* flesh out type annotations in synth_data and edit docstrings to reflect that types/defaults are now self-documented by the code

* notebook edits

* comment out undefined method for now

* change relative to absolute imports

* remove astropy_helpers vestige; packaging cleanups; set python_requires to >= 3.10

* update tox.ini to reflect new python_requires

* update CI workflows

* flesh out more type annotations

* add support for comma-separated strings to build line catalogs

* update dev notebook to reflect some api changes in linelists

* flesh out match_lines_wcs; save notebook dev

* actually commit dev notebook

* loosen typing on match_lines_wcs, but add sanity checking by casting input as np.array which needs to happen, anyway

* add routine to find arc lines and centroid them

* fix units in match_lines_wcs

* allow fwhm to be a float and assume u.pix if so

* fix line matching tests to ignore warnings and mark use of remote data

* add wavecal_demo notebook

* fix some post-merge issues

* fix column name to match

* demo notebook updates; codestyle fixes

* remove old numpy versions from tox.ini that aren't python 3.10 compatible

* tweak up min tested scipy version

* ignore new datetime warnings in python 3.12

* remove crutches for py312; don't seem to be needed anymore

* fix typo; clarify docstring; simplify check

* codestyle fix

* code now is using features that require python >= 3.10

* add warning to line_matching.py if the matched set is empty

* fix codestyle bug; remove mark from fixture in test_line_matching

* fix name in workflow
