NEF (NMR Exchange Format) I/O for synth-pdb.

This module now provides compatibility shims that re-export from the synth-nmr package.
For direct usage of NMR functionality, consider using synth-nmr directly:
    pip install synth-nmr
    from synth_nmr import write_nef_file, read_nef_restraints

See: https://github.com/elkins/synth-nmr
