Retransmission and rework crate (#6)

* Work to combine network and handler

Moving to a combined network and handler because it is required for retransmit

* Should not work but local cargo does not detect?

* Very large rework to make retransmission possible

Add retranmission and tests

* Small lib change

* Adjusted documentation

* Adjusted documentation

* Bumped version number to 1.5

* Bumped tokio version due to tokio issue readhalf unsplit

* Handle connack packet directly

* Cargo clippy and fmt

* Fix issue in state with connack

Vec would be cleared but would depend on items beting Some or None instead.

* Cargo fmt and clippy

* Adjusted code coverage generation

* Make tests and code coverage sequential
