scons 3 - examples do not compile

[Uzi Cohen]

due to changes in Scons 3 and up the object properties func_xxx are changed to __xxx__, all SConscript in the examples need to change func_code to __code__ (see line 18 in SConscript of examples/adc_single as an example).

On macOS, SCons 4.0.1 (via homebrew), I get this output:

stm32plus (master) $ scons mode=small mcu=f407 hse=8000000 float=hard
scons: Reading SConscript files ...

Not sure this is related, but I haven't used SCons before (I use PlatformIO, which wraps it under the hood), not sure where the problem is and how to deal with it.

To follow up - the problem is due to examples files using a Python 2 style iso v3. This batch edit fixes it:

sed -i '' s/func_code/__code__/ examples/*/SConscript
