* Add testing branch to workflow

* Add workflow

* Checkpoint

* Align SPI data rates in c++ code with Python code.

* Checkpoint

* CI fixes

* Update codeowners

* Workflow cleanup

* Rename to spi_rgb_led

* Rename header file

* Clang tidy

* Disable spi after transfer.

* Move enable() to where it belongs

* Call spi_setup before enable

* Clang tidy

* Add test

* Rename to spi_led_strip

* Include 'defines.h'

* Fix CODEOWNERS
