Support for ESP32 light sleep mode

**Please describe your use case for this integration and alternatives you've tried:**

ESPhome only supports deep sleep mode. i'm building battery powered sensors that are awoke by the use of PIR, waking from deep sleep activate the reset function and the whole board reboots upon motion detection.
support for light sleep or alternative sleep modes that permit this behavior is requested. (the board should wake up, fast connect to wifi send the "motion detected" signal and not have to reboot in order to do so.)
