Revised calcHTranspose operator

[johnmauff]

This PR represents a complete rewrite of the calcHTranspose operator. The previous implementation only stored the H matrix and accessed it using several indirect addressing arrays for the calcHTranspose operation. The previous storage format was non-standard and on large problems like the hurricane_4panel test case actually consumed more memory than just explicitly storing the H^t matrix. This PR changes the form of the calcHTranspose operator such that the H^t matrix is explicitly stored in a CSR format. This change enables both a reduction in memory usage for computationally large problems and execution time on the CPU. Due to reduction in memory usage, both the hurricane_4panel configuration can be run on 80GB H100 GPU's and the hurricane case can be run on a 40 GB A100 GPU without code changes. The version of the code has been tested on the following platforms and input configurations:

Derecho CPU

Derecho A100 GPU

beltrami supercell hurricane typhoonChanthu2020

@sjsprecious Thanks for your thorough review. I am fine with waiting for PR #66 to be committed first.
