Swift wrapper of SUI's TS SDK

Essentially it runs an internal JS runtime which compiles SUI TS SDK and exposes its methods on a callback fashion.

It includes an example iOS Swift application with example usage. Independently of this repo, it can be included in a iOS app by adding the dependency pod 'SuiSdk' of the published package.

The supported flows are zkLogin signing in through Mysten Lab's Enoki and then resolving transaction blocks as well as read operations on chain.

The full SDK can be supported by essentially exposing all required functions from TS SDK
