Pass a `linkTappedBlock` handler when adding multiple links to a single label

[PatrickDotStar]

This is necessary because the linkTappedBlock can't be set after a link got created using addLink(to:URL) method since the Link DTO is a struct.

It may sound pointless because we already have to pass an URL which then calls a delegate method when being tapped but we have a case where we add multiple links to a single label and each link press is handled differently.

@PatrickDotStar I'm not 100% sure I understand what you're trying to do with your code. Do you have an example you can post in here that will help me understand it?

[PatrickDotStar]

Sure. we have something like this which will get called in a for loop

// NantesLabel attributedString is something like = "one, two, three, four"
// We then want each word separated by ',' to have its own link tapped handler
// Since we only want one NantesLabel instead of adding multiple ones separated by ',' we have to do it like this

public class func addLink(to url: URL, range: NSRange, label: NantesLabel, linkTappedHandler: (() -> Void)? = nil) {
	if let linkTappedHandler = linkTappedHandler {
		label.addLink(to: url, withRange: range, linkTappedBlock: { _, _ in
			linkTappedHandler()
		})
	}
	else {
		label.addLink(to: url, withRange: range)
	}
}

Sorry it's taken me so long to get back to you!

LGTM @namolnad do you have any time to check it?

thanks @PatrickDotStar sounds like you're planning to add unit tests. will merge when they're good to go.
