Add community library link to readme

[arasan01]

What is the purpose of the PR?

I would like to add a link to the community library we have created.

Why did this work occur?

I am developing with swift-dependencies as a central part of my product. In this process, there was a lot of protocol-oriented development. So I thought Swift Macros could automatically convert this to Struct-based and realize function-by-function processing changes. We believe this will be of great help to projects with similar challenges.

Why create a separate library and then do a PR to add the link? Why not add this feature to this repository?

We believe this will help a great many people, but ideally as a pointfreeco library, this conversion is not even necessary. This is why we are creating it as a community library.

Definitely open to adding this, but given that we already have swift-dependencies-additions being a library extending swift-dependencies with higher-level dependencies, have you thought about naming the library more specifically related to the macros it offers?

I know renaming a library is a tall order, so no worries if you're happy with the way things are. Just lemme know and I'll merge when you're ready :)

@stephencelis
Thank you for thinking with me about naming to describe this library. We too have taken the opportunity to think about this once more.
It seems appropriate to position this library as a library that makes swift-dependencies more useful when using protocols. Therefore, we will change the name and description to be based on Protocol.
I also wanted to change the URL to reflect this, but considering that this is a bit of work and that the library itself is under my repository county, I compromised and left it as it is.
Thank you for your review!
