Add (hardware) production tests for the TK-1 and TP-1 (#69)
* ch552 firmware: add ch55x support files directly

* Add sdcc compiler to docker image, for building CH552 firmware

* Rework production test script

* Add menu-based test runner
* Rewrite production test flows as lists of individual tests
* Add both production flows and manual tests to menu

* Switch to using included binaries

* production test: Update message format
* test_txrx_touchpad: Retry if device communications fail
* production test: put all binaries in binaries/ folder
* binaries/top.bin: replace broken binary

* flash_check: Check for explicit flash IDs

* Document most test procedures

* Test plan documentation

* Sample udev rules

* Production test: allow external references to be overridden

* Remove outdated descriptions

* Correct shebang

* Update shebangs to comply with PEP 394

Change the python scripts to call python instead of python3, as this
works cross platform. See:
https://peps.python.org/pep-0394/#for-python-script-publishers

* Move production test to higher-level directory

* Clarify production test setup

* Move USB C connector test to separate directory
