Adding Continuous Integration

[ArminJo]

Here it is 😀 First I prepared it for stm32duino:STM32F1:genericSTM32F103C, but it can easily be extended to other boards.

• I corrected a forgotten change in DhcpAddressPrinter
• The examples Debounce,StateChangeDetection,Button,QASlave,InteractiveTest,WhileStatementConditional were excluded, because of QASlave.ino:61:21: error: 'BOARD_BUTTON_PIN' was not declared in this scope.
• The examples HardwareTimerOnePulseMode,HardwareTimerPWMInput,StringEx_Parsing were excluded, because of HardwareTimerPWMInput.ino:9:23: fatal error: Streaming.h: No such file or directory.
• The OLED_I2C library has a bug for all examples. and a lot more errors. To see all errors, just comment the line sketches-exclude: All results can be seen here.

There are 2 directories or ino files which must be renamed, to be Arduino compatible.

• A_STM32_Examples/examples/Communication/MIDI to Midi
• RTClock/examples/RTCAdj/ to RTCAdjust

Is there anything which speaks against merging this PR? If not, then I will merge it on Sunday at leteast.

I checked it again and it still runs without errors. I added workflow_dispatch for manual build check. This is a very handy feature I use sometimes :-) .

Great. Would recommend to simply do a ln -s instead of a copy of the repo. 😉

@fpistm Brilliant idea!
