Option to compile the UIFlow2 code

[BR123456]

This is a big one, but will make lot's of users very happy.
Add the option to compile the micropython code generated by the UIFlow2 IDE and load it to the controller (like in the Arduino IDE).
Development will be done using the current mode of using the firmware on the controller to run the micropython code (as an interpreter). This makes the development very convenient, user friendly and quick.
After the development is done, the user can compile the code to binary code and load it on the controller for best performance.
