Missing support for negative zero

[Janpot]

Came across this while evaluating this library. It looks like it supports Infinity and NaN (not sure if it's an oversight, but these are not included in the table in the readme), but it doesn't seem to support serializing negative 0.

const input = 1 / -Infinity; // -0
console.log(1 / input);
// -Infinity
console.log(1 / superjson.parse(superjson.stringify(input)));
// Infinity

Just of curiosity, when would you ever use a negative zero?

Personally I've never intentionally had use of negative zero, infinity, & NaN and prefer if a library throws whenever I encounter those as it's always just represented a hidden bug.

That‘s interesting! We should add support for this. Would you be open to provide a PR? I think it should be solvable by adding a new transformer in transformers.ts.

I'm sorry, I'm not planning to use this library in the near future. just thought I'd report an edge case I noticed.

No worries! Then this issue is up for grabs. Maybe someone else wants to take a shot at it :)
