	Full version in ROM ELF's filenames (major * 100 + minor). E.g:
	esp32_rev300_rom.elf is for version 3.0
	esp32c3_rev3_rom.elf is for version 0.3
	Fix esp32c2 revision to 1.0


todo:
 x reinstall esp-idf fucking again to test the reinstall script
 x run dump on freenove fuckin again (twice) with latest for testing and final binutils
 x run dump fuckin twice on another esp32s3 for compare
 x save the shit and back the shit up
 x add and push git projects
  - document lmfao
 - study the fuck out of cuork's c3 exploit
 / get on that fuckin binary exploit lmfao
