[Stm32flash] release plan

The plan is to release 0.6 rather soon with what is in git now. It has several improvements since 0.5 and above all many new devices supported. Testing and feedback is welcome. I have tested basic functionality with STM32F103 on Linux, Windows 10 and macOS 10.13. There are many patches and merge requests in the tracker but these will have to wait for later releases, to not delay 0.6 indefinitely.
