wake-from-isr

Only enable if you plan to use the edge-executor crate

Affects interrupt::embassy_sync…

adc-oneshot-legacy

Temporary, until (https://github.com/espressif/esp-idf/issues/13938) is addressed

When enabled, the code for the legacy ADC oneshot driver will be compiled;

When not enabled (default) the code for the new ADC oneshot driver will be compiled;

Since we don't wrap the legacy continuous ADC driver, the new continuous ADC driver is always compiled.
