Summary

Major changes:

• feature 1: Parsing and storage of vibrational modes within a JDFTXOutfileSlice
  -- Stored as a list[dict], where each dict contains
  --- "Type": str
  ---- either "Imaginary", "Zero", or "Real"
  --- "Type index": int
  ---- (Base 1) index of the mode among other modes of the same frequency type
  --- "Degeneracy": int
  ---- Degeneracy of the mode (ie if mode["Degeneracy"] == 2, than there is one other mode in the list with the same frequency)
  --- "Frequency": float | complex
  ---- Frequency of the vibration in eV
  --- "IR intensity": float
  ---- IR intensity of the vibrational mode in e^2/amu as derived from dipole of the vibration
  --- "Displacements": NDArray[float]
  ---- Displacement vector representing the vibrational mode (converted from Bohr to Angstrom as magnitude of vector is a input variable for vibrational analysis in JDFTx)
  -- Testing for vibrational mode parsing
• feature 2: Parsing and storage of vibration energy components within a JDFTXOutfileSlice
  -- Stored as a dict[str, float], containing
  --- "T" : Temperature at which free energy was evaluated (in K)
  --- Dumped free energy components in eV
  -- Testing for vibrational energy components parsing
