tessreduce/#__init__.py# (an editor backup file) and tessreduce/web path were accidentally committed and aren't part of the package. calspec_mags.npy is listed in MANIFEST.in but no longer exists on disk. None of these are referenced by any code.
sector_mjd.csv required manual updates every time new sectors were scheduled (most recently extended through sector 107 by hand). It's replaced by tesswcs.pointings, which ships an actively maintained sector pointing table (currently covering archived and predicted sectors through 121) so this no longer needs repo maintenance. Also replaces tess_stars2px_function_entry (the tess-point package) with a tesswcs-based sector/camera/CCD lookup (WCS.from_sector + footprint_contains), since tesswcs supersedes tess-point and this avoids depending on both. Verified against tess-point's output for a reference target (same sectors/camera/CCD, pixel coords within ~2px). Adds tests for the two new helpers (_tess_pointing_table, _target_sectors) covering table structure, a known sector's start time, expected sector matches for a reference target, and array alignment/pixel bounds.
Classifiers listed Python 3.6 despite python_requires>=3.9 and no newer versions; replaced with 3.9-3.12 and dropped the untested PyPy classifier. Pinned tesswcs>=1.8 since the sector lookup relies on WCS.from_sector/footprint_contains, both confirmed present at 1.8.15. README image links were relative paths that render broken on PyPI's project page (which doesn't rewrite them like GitHub does); switched to raw.githubusercontent.com URLs.

sector/camera/CCD lookups. Verified against tess-point's prior
output for a reference target and added regression tests for the
new lookup helpers.
