Epic: Refactor Export Services in VCell

[CodeByDrescher]

Problem

VCell Export code mostly works, but is unwieldy. What once started as a simple export feature has had additional features added in a quick but haphazard manner. Our work in adding N5 export has demonstrated that development with the exporter is slow, due to the difficulty in working with the relevant code base. Even now, Spring salad and N5 do not nicely fit into the existing code, and we are only making our work harder down the line.

Solution

Refactor the code in the Export-relevant part of VCell to simply the design, improve the ability to fix bugs and add new export formats. Not only should this make future development easier, but users should also see a decrease in export time for some formats.
