Note that this is protocol breaking, because of PB changes breaking backward compatibility. Thus the protocol ID/version has to be changed

[Wondertan]

We also should not merge this in main before the upcoming release. Let's keep multiple breaking changes for HeaderEx protocol together and not spread those over multiple releases to avoid joint headache

Is the underlying impl of stream here yamux? If it so, then

// SetReadDeadline sets the deadline for future Read calls.

[Wondertan]

The commit and the PR name should have an exclamation mark pointing to this PR as breaking. Other then that, lGTM

[renaynay]

Please increment exchange protocol version

[renaynay]

All tests passing besides integration (which is expected).
