Implement Uni/Custom Links (uni_links) in iOS

[immadisairaj]

Deep Linking is available in android but not in iOS. Implement deep link in iOS.

Dependency used is uni_links.

Methods are already implemented for android. So, for iOS mostly only setup is required.

This might require to upload apple-app-site-association file to the host(dl.radiosai.org) which we have no control of. Can possibly try to achieve using custom url schema.
