[clone] move packet-line code into own crate

This is when I learned that there is also a long-running processes
format that uses packet-line to communicate.

Thus it doesn't belong in transport anymore, which was the previous
'best fit'.

Since it's a serialization format, setting up its own crate makes
quite some sense.
