Regenerate sdkconfig.<board> if missing

[maxgerhardt]

I just wanted to apply a new sdkconfig.defaults file (from https://github.com/espressif/esp-idf/tree/v4.3/examples/bluetooth/bluedroid/classic_bt/a2dp_sink/main), but I already had a sdkconfig.pico32 in my project folder after an initial build. So, wanting to apply the defaults file, I deleted sdkconfig.pico32 in hopes that the next pio run -t menuconfig regenerates the default options plus the options from the sdkconfig.defaults -- instead it gives an assertion error that the file is not found

>pio run -t menuconfig
..

I think the behavior should be changed to generate the file if missing, while respecting the .defaults file.

Using latest Espressif 32 (3.3.0).

Thanks for reporting, should be fixed in the dev branch!

I've just tested this and the regeneration, while respecting the sdkconfig.defaults file, works like a charm. Thanks!
