About transition to federated plugin

[Skyost]

This issue has been created to keep talking about #9. So, as I said in #9 (comment), I have done refactoring in cea115a and 5556a7b :

• Moved all source files into the src directory.
• Renamed BonsoirPlatformEvents into BonsoirAction (to avoid confusions with BonsoirEvent).
• Merged MethodChannelBonsoir and BonsoirPlatformInterface because I thought it was not needed to have an abstraction for BonsoirPlatformInterface (but I'm not that sure about this one).

What do you think about it @Piero512 ?

This is very bad.
The merge of platform interface with the method channel is bad, other plug-ins don't necessarily need to use a method channel to implement a platform interface, so it should be separated. See
https://github.com/flutter/plugins/tree/master/packages/url_launcher/url_launcher_platform_interface/lib as an example.

I see. I reverted the change in 0b0475e.
