Remove singleton so multiple items can be initialized.

Our use case doesn't require multiple audio streams to be playing at the same time. But multiple audio files are just listed on a page as attachments. Right now with the singleton, it makes loading each one difficult. This was possible on v3 and worked ok. Making it a singleton removed a lot of functionality related to that and feels like a step backwards.

Thanks for the feedback 🙌 Totally agree — Nitro makes multiple instances and a hook API very doable.

Right now I’m experimenting with this in #707, where hooks are being added in a way that already allows creating multiple instances. The design is still early, but the event-first API makes it more natural to support this. The PR is about to be merged and will be released as v0.2.0, so please keep an eye on that.

👉 Also, the library has just been rebranded to React Native Nitro Sound. It’s still the same codebase for now (so no major breaking changes), but I expect more structural updates. In particular, the plan is to split sound and recorder into independent, composable APIs so we can support more flexible extension and cleaner multiple-instance handling in the 1.0.0 release.

Would love your input as we move in this direction.

@phazei I'll close this in favor of #677
