Added a note how to modify ESP-WROVER-KIT V3 hardware to improve flash bus signal's integrity when using 80 MHz flash frequency. Due to length of the signal lines the flash mode QIO + 80M is not stable and may cause random exceptions on the ESP-WROVER-KIT.

The module's flash bus is connected to the pin header JP13 through 0-Ohm resistors R140 ~ R145. If the flash frequency needs to operate at 80 MHz, to improve integrity of the bus signals, it is recommended to desolder resistors R140 ~ R145. At this point, the module's flash bus is disconnected with the pin header JP13.
