Great to learn at TESS SciCon that this functionality is ready! I tried to run example code from the readme, and the call prf = lkprf.TESSPRF(camera=1, ccd=1) failed with error

OSError: FITSIO status = 105: couldn't create the named file
failed to create new file (already exists?):
/Users/keatonb/anaconda3/lib/python3.11/site-packages/lkprf/data/tess-prf-1-1.fi
ts

I inspected that path and there was no "data" directory in the lkprf directory. I added it manually and I was able to run the TESSPRF function successfully. I'll make a PR.
