Locate and rename spectra with identical filenames

[hover2pi]

Some of the spectra files have the same filename, e.g. 'u40008.fits' for both an optical and NIR spectrum. The metadata is correct for these files (about 40 of them) but the file path in the SPECTRUM table is too generic.

Someone must:

1. Find the files using the db.clean_up() method on the SPECTRA table,
2. Change the filename(s) in the BDNYC_specra directory, and
3. Update the spectrum column in the table to reflect the new filename(s)
