Ability to specify whether to reboot after writing bin to flash #497

Thanks for your work on the project!

I'm working with an ESP32-S3 core on a project where I need to flash three .bin files, all over 1MB, to three separate locations in memory. Currently, the write_bin_to_flash method forces the device to reboot after each method call (link), which causes a communication failure error when I try to write at the next location.

I am looking for the ability to specify that the device should only restart after the last call to write_bin_to_flash. I would assume this would require a new parameter.

Hi! I've just implemented #561, which might help here (although it might not be a full solution, I think). You could use --after no-reset or --after no-reset-no-stub to avoid the reset after every write. I'd appreciate it if you could give it a try.
