Support Inf and NaN in models

[hhaensel]

Currently, Inf and NaN cannot be transmitted through JSON although javascript natively supports Infinity and NaN.

This issue relates to GenieFramework/StippleUI.jl#135

I've submitted a PR to JSON3, that would make adaptation much easier, let's see whether they like it.
quinnj/JSON3.jl#292

The PR is still pending, but on Stipple's end everything is prepared.
You can test it by using the main branches of Genie, Stipple, StippleUI and StipplePlotly and by using my JSON3 branch
