Can ABACUS support ELF output?
Background
Electron localization functions (ELF) can be understood as a measure of the effect of the Pauli repulsion and used to do chemical bond analysis. ELF has values between 0 and 1, where 1 corresponds to perfect localization.
Describe the solution you'd like
Only the charge density, density gradient and kinetic energy density are needed. The output file format is cube.

In my recollection ,ELF can be calculated by Multifwfn? @kirk0830 So this is a request for ABACUS-Multiwfn interface

@QuantumMisaka Multiwfn needs MOLDEN file format, while the transformation from numerical atomic orbital or PW to GTO seems not ready for ABACUS, but I indeed have plan to do that.
