wrappedJsonParse may be causing an issue with certain reforms

[anth-volk]

Unclear yet as to what, but if running locally and following the below link, it appears that wrappedJsonParse fails. This is a bit strange, since all it's doing is running JSON.parse(), with an added reviver to convert String-typed "Infinity" into Number-typed Infinity.

Update: The driver of this is that the labor supply response output JSON looks like this:

We get an 11th decile (could be fixed by PolicyEngine/microdf#234) and we get NaN values for deciles 1, 9, and 10 of the total average income and substitution effects.

This will almost certainly be either -us or -api. I'll transfer the issue when that becomes clear.

Finally got some clarity on this. This may be a -us issue, as even when running the country package locally, household_market_income returns NaN for a small subset of records. This is then scaled up to entire deciles being equal to NaN due to the formulas that are used within the API, and then these deciles are returned as NaN, which JSON has no way of deserializing, causing the front-end crash.

I'll look more into the individual components of household_market_income either Saturday or Sunday and see if I can figure out what's going on.
