Add support for JC3248W535C (Guition 3.5" ESP32-S3 Display) (#189)

* Guition Display outputs to screen

* Fix Display Flushing and Touch Screen works now!

* fix UI rotations

* set default orientation to 2

* Start trying to implement horizontal software rotation

* remove -w flag

* cleanup

* Rename to JC3248W535C

* Update lv_conf.h

* replace URL
