Allow factory reset over serial

[rrooggiieerr]

Describe your core improvement

I would like to be able to factory reset my devices over the serial connection using the esphome cli. Currently I have implemented the Factory Reset component that creates a button in HA that allows me to factory reset the device, but that takes to much time when resetting 100 devices and it creates a potential risk of accidentally triggering the button and thus unwanted factory resets.

esptool --chip esp32 erase-flash flashes the whole flash, which is a bit to much.

Would be cool if the esphome cli would contain an option to do the factory reset as implemented by the Factory Reset component

Current limitations

You can't factory reset using the CLI

Technical benefits

Makes it easier to quickly factory reset a bunch of devices. Also think about resetting a device to default after testing
