Migrating to "Flutter Network" Org

[daadu]

Hello everyone 👋

We (@alternadom and me) have decided to move this repo to a new Github org called "Flutter Network". It is to consolidate all networking-related flutter plugins in one place.

The transfer will be done as following:

• transfer WiFiFlutter Github repo from @alternadom to @flutternetwork
• transer wifi_iot plugin from alternadom.com to flutternetwork.dev publisher
• correct all links inside README and code
• credit @alternadom as "original author" of the package
