validate pins in python.

* Can't use match/case with Python 3.9.
Check for inverted pins.

* Optimize write_array16

* Show errors in hex

* Only one spi on ESP32Cx variants

* Ensure bus is claimed before asserting /CS.

* Check on init/deinit

* Allow maximum rate write only SPI on GPIO MUXed pins.

* Finger trouble...

* Make comment about missing SPI on Cx variants

* Pacify CI clang-format. Did not complain locally??

* Restore 8266 to its former SPI glory

* Fix per clang-format

* Move validation and choice of SPI into Python code.

* Add test for interface: config

* Fix issues found on self-review.
