3b079c91bf T5-4.7-S3 Epaper Pro support (#6625)
* preliminary io pin definitions

* Update product link

* Move to new variant structure and refactor inkHUD - Display does not work and SX1262 init fails on HT752-02

* update variant definitions

* add EPD driver

* fix lora, add v1/v2 variant targets

* adapt pins for v1/v2

* alt button

* add compile guards

* use lilygo epd47 lib

* workaround for INT ERR_NOT_FOUND

* USE_EPD (e-ink parallel display)

* use FastEPD driver

* create screen

* EInkParallelDisplay definition

* setup screen

* dispaly() implementation

* enable touchscreen

* rotate touch screen

* refactor display buffer processing

* provide local copy of TwoWire instance as the touch driver calls end()

* use larger fonts

* replace touch driver; enable debugging

* replace touch driver; enable debugging

* consider bitsremain == 0

* tryfix crash

* fix button

* update touch driver

* set lora_cs pin

* update touch driver and lib reference

* add locks

* limit Ghosting similar to EInkDynamicDisplay

* workaround for FastEPD partial update bug (artifacts)

* display() code cleanup

* fix a few platformio definitions

* more EPD display cleanup

* set rotation

* use FastEPD arduino I2C by default

* touch rotation

* update screen for EPD

* increase swipe distance for larger screen

* EPD UIRenderer

* trunk fmt

* further #ifdef USE_EPD

* disable rotation which messes up w/h; more cleanup

* switch off ghosting algo

* releease build; V1 buttons

* swap V1 buttons

* rearrange USE_EINK/EPD macros, use large font

* cleanup (revert modified files)

* more cleanup

* revert

* revert file

* revert file

Removed redundant line continuation in preprocessor directives.

* Temporary gate off PSRam calculations until we can fix them

* move variant.cpp and update commit references

* revert wrong merge

* add earlyInitVariant()

* initialize all port 0 pins (0-7) as outputs / HIGH
