Marlin 2.0.6

For this release we focused on compatibility with a wider range of boards and controllers, especially STM32-based boards, color screens, and touch screens. With so many new files being added, a lot of work has gone into optimizing the PlatformIO build by peeking at enabled features and only downloading libraries and compiling code required for your enabled options. And we tackled a whole host of issues from stepper timing and interrupt priority down to the details of controller-wheel responsiveness.
