Regenerated SAD guess with QUICK-21.03
Regenerated SAD guess with QUICK-21.03 for all main group elements Deleted SAD guess files for transition metals. These converge very slowly (hours to days) and may be added later.

Update SAD guess files for all basis sets added after release of QUICK-21.03.
Closes #399
Reason: The old SAD guess routines were replaced after release of QUICK-21.03 to improve performance. SAD guess in QUICK-21.03 can take hours to days for a single atom for larger basis sets. However, the new SAD guess produces wrong results. As such all SAD guess data added after release of QUICK-21.03 is wrong.
SAD guess has been recomputed using QUICK-21.03 and updated for following basis sets:
A few SAD guess files were deleted. These are for very slowly converging (in QUICK-21.03 SAD guess) elements. See issue #385 for missing SAD guess data.
As an example, below is the SCF for caffeine with def2-TZVP (input taken from test opt_caffeine_b3lyp_3-21g and basis set changed). Calculation using QUICK-24.03 on Expanse single A100 GPU.
Compare to this output with the updated SAD guess files:
The initial electron density and energy is much closer to the converged result. The SCF converges in 11 vs 17 iterations and takes 145 instead of 256 seconds.
