feat: Explode query string

🐸 Problem to Solve

OpenAPI 3 accepts parameters whose schema is an object. When passing data to a fetch function, nested query values get stringified as [object Object].

👑 Solution

This change extends the existing query params encoder. It can now express nested objects and arrays in addition to scalar values.

It uses the form-style query parameter encoding which is the default style for query parameters.

🔧 Changes (and non-Changes)

• scalars are encoded as before
• lists are still exploded; however…
• lists are exploded recursively
• objects are exploded recursively

I included a bunch of examples in the tests for the src/explodeQueryFormStyle.ts utility. I also added validation of url-encoding behavior in the fetcher tests.
