PR Summary

Refactors the helper function _vertical_remap_extrap to avoid problematic for loops over the vertical levels and addresses some warnings related to specification of chunks, dimension specification with argmax, and intentional interpolation out of bounds.

While this seems to address the most significant issues in terms of performance / execution time, there's still some clean up to be done in interp_hybrid_to_pressure and it would be nice to have a benchmark to cover this.

I did also replicate the poor performance with a larger example on my laptop in addition to the HPC system.

Closes #591
