LDOS calculation is needed

[Luc1anoo]

Background

I'm tring to perform STM calculation using ASE.STM module. I have done the calculation using GPAW as calculator. When I try to change the calculator to ABACUS, the error thrown:
Traceback (most recent call last):
File "/personal/ABACUS-cases/10/stm_ABACUS/stm_ABACUS.py", line 72, in
x, y, I = stm.scan2(bias=bias, z=height, repeat=(5,5))
File "/opt/mamba/lib/python3.10/site-packages/ase/dft/stm.py", line 163, in scan2
self.calculate_ldos(bias)
File "/opt/mamba/lib/python3.10/site-packages/ase/dft/stm.py", line 68, in calculate_ldos
ldos = np.zeros(calc.get_pseudo_wave_function(0, 0, 0).shape)
AttributeError: 'Abacus' object has no attribute 'get_pseudo_wave_function'

I checked the source code of ASE.STM (Source code for ase.dft.stm) and found that the error may be due to the lack of LDOS calculation feature in ABACUS.

Describe the solution you'd like

Add LDOS calculation feature.
