When idf.py coredump-debug is launched with '--core' argument, it
tries to determine the file format (raw, elf, b64). To detect the
'raw' core dump the code checked if the version word matched one of
the known values.
However, the version word also contains the chip ID in the high
half-word, so the check failed for anything other than the ESP32.
The detection of core file format has been moved to esp-coredump
package in version 1.9.0, including the fix for chip ID.
