LammpsData.from_file does not read in bond types, angle types, etc.

[tawe141]

Describe the bug
Reading a LAMMPS data file via LammpsData.from_file() does not read in the bond types, angle types, dihedral types, and improper types.

To Reproduce

from pymatgen.io.lammps.data import LammpsData
ld = LammpsData.from_file(filepath)
print(ld)

gives the output:

Generated by pymatgen.io.lammps.data.LammpsData
174  atoms
201  bonds
420  angles
438  dihedrals
 54  impropers
107  atom types   # bond types, angle types, etc. should be below this line
