feat: iOS Identity Document Provider

[PhearZero]

Overview

TLDR: Add iOS support 😅

WWDC25 announced the Digital Credentials API and it is similar to the provider from Android. Any chance that this lands in this package or is this just for experimental purposes?

I think it makes sense to add this! We should think about how to handle the different protocols, currently this library mainly supports the OpenID4VP protocol, and not the ISO 18013-7 protocol.

I think we can define a new type representing an ISO 18013-7 request instead. Our wallet doesn't support the 18013-7 protocol yet for the DC API, so I don't think we will work on this in the coming weeks (maybe in the fall).

Pull requests are welcome though!

Hi @PhearZero! We do not have a deadline yet, but we do intend on starting this work very soon. Including some basic integrations into our wallet which you can use as an example.
