flash algorithm failed with code 1 on ESP32-C6 if flashing to 0xC10000, works fine up to 0x1B0000

[dragonnn]

Describe the bug When trying to flash an image on ESP32-C6 16MB to a custom address using --base-address option if the address is 0xC10000 it fails with flash algorithm failed with code 1

To Reproduce Steps to reproduce the behavior:

1. Run probe-rs download --chip esp32c6 --binary-format=bin update.bin --base-address=0xC10000
2. To compare run for example probe-rs download --chip esp32c6 --binary-format=bin update.bin --base-address=0x010000 this works fine
3. From my tests it starts breaking at 0x1C0000, 0x1B0000 works fine

Expected behavior Flashing should end successfully.

Additional context Using espflash to write to 0xC10000 works fine:

espflash write-bin -c esp32c6 0xC10000 update.bin -p /dev/ttyACM0                                                                                                                                                      ─╯

I was wondering if flash_size in IdfLoader is detect right but I did verify that probe-rs does pick up FlashSize::_16Mb with should be fine.
