Subject: [PATCH] fix: Fix the ESP32-S2 security info response size (#73)

The ESP32-S2 ROM GET_SECURITY_INFO
response does not contain chip_id and api_version fields.
Currently, the flasher stub just returns 0 and 0 for these, however
chip_id 0 is reserved for the ESP32.
This makes the stub behavior in line with the ROM.

Closes https://github.com/esp-rs/esp-flasher-stub/issues/65
