Allow bidirectional exchange of files

[nidhal-labidi]

Description

The previous limitation of one-way communication restricted the library’s applicability in scenarios requiring real-time bidirectional file exchange. We need to find a way to allow bidirectional file transfer.

Tasks / Definition of Done

• Refactor the code of the classes FlottformChannelClient, FlottformChannelHost, FlottformFileInputClient and FlottformFileInputHost so that it allow us to build multiple use cases on top of it in the future.
• Build a simple app to show how the bidirectional file transfer works.
• Update the other projects (for example demo.flottform.io) which are using the old version of file transfer.
