This PR adds several new routines for turbulence-related spectrum calculations in staggered compressible FHD.

  1. Computes spectrum of scalar quantities (such as pressure, temp, concentration) in addition to kinetic energy
  2. Decomposes the velocity field into solenoidal and dilatational components, and computes separate Fourier-space spectra for both.
  3. Additional diagnostics of the gradients of solenoidal and dilatational components of the velocity.
  4. Staggered compressible FHD turbulence now outputs separate velocity components, along with vorticity and divergence of the velocity fields.
