Support multiple query parameters with the same name about huma HOT 3 OPEN

@csmarchbanks I'm open to trying to support this. I didn't originally implement it because of performance reasons, i.e. you can avoid all dynamic allocations in the request handling hot path by only having one value per query param name. I think returning []string will require allocations, but I'm open to ideas. The benchmarks in adapters/humachi can be helpful to see how your changes impact memory and garbage collection.

Edit: another option is to support escaping of commas.

I'm trying to support the same thing. Currently it is supported by OpenAPI with the parameters "explode: true" and "style: form" (https://spec.openapis.org/oas/v3.1.0#parameter-object). I tried to add these annotations but the resulting json always have the explode property to false, and was confused until I stumbled on this thread.

EDIT: Found the exact line

I'm also encountering this block. I'm happy to help with code review / testing / etc.
