Flashing over JTAG with TIAO multi function adapter

[ESP_Alexey]

Filed this PR against the openocd-esp32 project to increase the timeout to 10s. Seems to do the job.

This will be fixed. Corresponding changes are under review. For now, if you can build openocd-esp32 yourself you can increase ESP32_ALGORITHM_EXIT_TMO constant in openocd-esp32/src/flash/nor/esp32.c.

Exactly, the linked PR has been working reasonably well for me, have had no issues flashing since this change.
