* Add F5 target, lp5562 driver and api-hal-light. Update api-usage, switch to F5 by default. * API HAL: add i2c and hardware version api. Dolphin: show hardware version. * OTP version generator and flashing utility. * Assets script: fix code formatting * Backport F5 changes to F4 * F4: disable insomnia, prevent damage to BLE RX path * F5 HAL API Light: remove magic delay to fix magic BLE * Dolphin: HW target validation on start * invert RSSI indication in sub-1 * API HAL: rename board to body in version api * Gpio tester: detach and release viewport on exit Co-authored-by: aanper <mail@s3f.ru>
