Tuya: Fix init sequence and handle wifi test command (#820)

Browse source 
* Handle WiFi test command

Also rename commands to match Tuya protocol docs

* Fix init sequence and product info check

* Fix clang-format suggestions

* Additional changes based on code review

* Fix temp command buffer scope

* Let the interval timer fire the first heatbeat

* Fix init steps; add logging

* Lint

* Remove setup_priority override

* Add delay to dump_config

* Refactor dump sequence

* Fix verbose logging

* Fix lints

* Don't bother suppressing duplicate config dumps

* nolint
