This PR adds Windows support for Bonsoir.

This PR fixes #21.

This is what needs to be done before merging :

• [x] Find a way to dispose all broadcasts and discoveries on close. This is done using detachFromEngineForRegistrar on Darwin, I don't know what's possible to do on Windows.
• [x] Handle TXT records for discovered services. I don't know if we should report them before or after having found them.
• [x] Don't bundle dnssd.lib. We can use @Piero512's FindBonjour.cmake (https://github.com/Piero512/bonjour_ffi/blob/main/cmake/FindBonjour.cmake) to achieve this. We'll use WinDNS.
• [x] Fix remaining bugs.
• [x] Format everything (my clang-format isn't working...).
• [x] Correctly update plugins versions.

Hello!

That FindBonjour.cmake was some code I found, and I adapted to my POC, but uh, I think it's someone else's and I guess licensing would be important to you.

Anyways, I found a source, https://accserv.lepp.cornell.edu/svn/packages/root/cmake/modules/FindBonjour.cmake, and the respective license https://accserv.lepp.cornell.edu/svn/packages/root/LICENSE

Also, would this Windows support require the user to install Bonjour? Because that would be annoying.

Well, I was thinking about that and I'm currently rewriting it to use WinDNS. Will commit it soon.
