Support data parsing from popular DFT softwares.

### Background

Maybe Vasp or Openmx?

### Describe the solution you'd like

Just implement one other data parsing function.

### Additional Context

_No response_

No files, tests, or existing parser entry points are named. Start by locating the current data-parsing functions in DeePTB and compare their supported formats with VASP or OpenMX outputs. Done means one additional DFT software format is parsed correctly, with its expected data made available to the package.
