VCell Export needs a face-lift

[CodeByDrescher]

There's a few tasks regarding this issue:

• [ ] VCell CLI has a 50% slowdown in export compared to GUI
• [ ] The code surrounding export almost 2 decades old, and could use a re-write with modern best practices.
• [ ] There are some inefficiencies discovered with exporting in general, and fixing them could speed up export times on large sets of data.

Decisions need to be made as to what formats are high priority for export functions and which should be dropped/discarded as no longer useful. For example, JPEG should be discarded, as well as some movie outputs. Should spend some time as a group going through the possibilities and making decisions.
