Request: `auto` option for `init_wfc`

[QuantumMisaka]

Waiting for init_wfc auto option to solve the bug below

Describe the bug

After #3140 , We can use init_wfc file and init_chg file when the file is not exist, ABACUS will skip the reading process and do calculation. But in the 3.7.0 version, the wavefunction part have problem and cannot skip properly:

 Read in wave functions files: 8
Can't find the wave function file: WFC_NAO_K1.txt
 
 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
                         NOTICE                           
 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
 
 Failed to read in wavefunction.
 CHECK IN FILE : OUT.ABACUS/warning.log
 
 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
                         NOTICE                           
 !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
TIME STATISTICS

while the charge part maintained.

 START CHARGE      : file
 WARNING: Failed to read charge density from file. Possible reasons: 
 - not found: The default directory of SPIN1_CHG.cube is OUT.suffix, 
or you must set read_file_dir to a specific directory. 
 - parameter mismatch: check the previous warning.
 Use atomic initialization instead.
 DONE(13.1617    SEC) : INIT SCF
 * * * * * *
 << Start SCF iteration.

Expected behavior

The init_wfc file function should work like init_chg file , when the wavefunction file not exist, the init part should skip back to atomic.

To Reproduce

Run with init_wfc file

@pxlxingliang @hongriTianqi could you have a look?

Hi @QuantumMisaka, set init_wfc to file and abacus can do calculation continue even the wfc file does not exist, this may confuse some user. Recently, I am changing the behavior, and ABACUS will stop and quit if the file does not exist. For your demand, I think it is better to add another option to meet it.

For init_chg, #4560 will add option auto that behavior as you expect, and for init_wfc I will also add one option recently.
