After starting to get some progress on a test CLI (with both sending and receiving sides), we can now encrypt/send, and decrypt/download chunks on storage.

I will make a few changes on how files saving will be handled because for now the receiver only get chunks data, and don’t know how to reassemble them.

If you want, one of my git commit got this long ahh description:

- Many more checks
- Receiver can set their name (sender get notified)
- Chunks are sent to receiver - receiver can acknowledge when they receive one, and chunks sending is paused if they have at least three chunks not ack.
- An encryption protocol indicator is exchanged (not encrypted) to let clients know what encryption parameters to use
- Chunks that are in the memory of the server has a maximum, afterwards we stop accepting more
- Auto removal of all in-memory data of acknowledged chunks
