fud dependency on calyx-py

[eys29]

I think this recent push adding an import from calyx reintroduces the issue here.
I was having trouble reinstalling fud.

The command fud config --create global.root <full path to Calyx repository> would complain about import calyx in json_to_dat.py and interpreter.py.

I tried removing the import calyx lines in these two files on this branch which allows the fud config command to run but then fud -e obviously can't import the numeric types.

@eys29 CAPRA slack links are not accessible from this page. Can you update the issue to be self-contained?

Also, this happened because of a recent merge (#1715). You need to install calyx-py to make fud work now (which is kind of annoying I guess): https://docs.calyxir.org/builder/calyx-py.html#installation

Thanks @rachitnigam for pointing that out! Installing calyx-py fixed that.
