Examples do not compile on windows

[countcb]

Thanks for creating this binding!
I am currently taking a look at it to see if I can replace zig-gamedev/zflecs with this.

When trying to compile the examples on my windows machine I noticed, that the examples fail to compile because of linker errors.
To my understanding, flecs includes a web based explorer to inspect entities and a built in http server.
On windows this requires windows sockets and therefore ws2_32.

I created a pull request that includes ws2_32 on windows builds:
#1

With this fix the examples compile and run also on windows.
Feel free to merge this in.

This should probably also be added to the readme as well.

Don't know if you want to add one, both, or none of these changes, so I created an additional PR with just the readme update:
#3
