Creates a docker image for stm32 CI.

Edit and run the build.sh script, then upload to dockerhub.

See the stm32template readme for instructions on how to install the prerequesite IDE and FW.

Note that your local IDE installation will accumulate bloat (updates and plugins) as you use it, so if you'd like to minimize the size of these docker images, you can reinstall a pristine copy of the IDE in another path (e.g. ~/st/docker/stm32cubeide_1.5.1 instead of ~/st/stm32cubeide_1.5.1), then edit the build.sh script to point to that pristine copy.

Contains:

• STM32CubeIDE
• Firmware for F4 line. Feel free to fork and customize for your purposes.
• clang-format for detecting formatting errors
• cpputest for unit testing
• lcov for code coverage
