[Help needed] fixing ImportExport family config for Revit 2023+

Hi pyRevit Comunity,

I have been trying to fix the import export family config tool, but haven’t had enough spare time nor competence to fix it in a timely manner. I started like so:

Anyone interested in helping me fix it? Or willing to fix it entirely by himself?

It is mostly fixing parameter units and storage types.
There is also one things that is missing: importing and setting family selectors, but that is a big one I think.

Here is the wip PR

If interested in testing.
The latest wip installers do provide a fix.
Feel free to test and report back here if anything
