tools/flash_board.py: flash another board over USB and give it its own identity

Browse Source 
Picks the port, checks ESP32-P4 / chip revision against the image header /
32 MB flash, optionally erases, writes the images from build/flash_args,
reads the boot log for the IP and sets hostname, stream/Spotify name and
multicast address over the API. All questions also work as options.

- Flash over the network (normal way since step 2b; keep USB for recovery):
`curl -f --data-binary @build/aes67_p4.bin -H 'Content-Type: application/octet-stream' http://p4-aes67/api/ota`
The board reboots into the new image on trial; check `GET /api/ota` shows the new version with `pending_verify: false`.
- Another board, over USB: `tools/flash_board.py` (checks chip revision and flash size, optional erase, flashes, finds the IP in the boot log, sets hostname / stream name / multicast so boards don't clash). Needs a build and esptool (IDF env or `pip install esptool`).
- Serial: opening /dev/ttyACM0 can reset the board. Don't open it while an OTA image is on trial (a reset then counts as a failed boot and rolls back).
- Rollback test build (self-test always fails), in its own build dir:
`idf.py -B build-selftest-fail -DSDKCONFIG=build-selftest-fail/sdkconfig -DSDKCONFIG_DEFAULTS="sdkconfig.defaults;sdkconfig.selftest_fail" build`
