Screen flip function was useful in some applications that use mirrors.

Add flip flag added to setRotation() function.

void setRotation(uint8_t r, bool flip);

Only tested on 1.3" TFT screen with 7 pins.

Found this because I was using this: https://docs.espressif.com/projects/esp-idf/en/latest/esp32s2/hw-reference/esp32s2/user-guide-esp-lyrap-lcd32-v1.1.html and everything was mirrored. I know this PR is old - but wanted to express my thanks as it got me out of a hole :)
