- Added GUITION ST7701 panel instructions.

[FigueiredoStable]

Just add a new device support for ST7701 manufactured by GUITION, link: GUITION Smart Display

* The board:

* Before the new instructions, colors were inverted or only rendered a partial size of the screen:

* After added instructions by manufacture

both ::init() methods are identical; since LGFX has a desing pattern for display variants, let's create a Panel_ST7701_Base to handle the redundant ::init() and make both Panel_ST7701 and Panel_ST7701_guition_esp32_4848S040 inherit from it:

lgfx/v1/platforms/esp32s3/Panel_RGB.hpp

  struct Panel_ST7701_Base : public Panel_RGB
  {
    bool init(bool) override; 
  };

  struct Panel_ST7701 : public Panel_ST7701_Base
  {
  protected:
    const uint8_t* getInitCommands(uint8_t listno) const override;
  };

  struct Panel_ST7701_guition_esp32_4848S040: public Panel_ST7701_Base
  {
  protected:
    const uint8_t* getInitCommands(uint8_t listno) const override;
  };

lgfx/v1/platforms/esp32s3/Panel_RGB.cpp

• create Panel_ST7701_Base::init(bool)
• remove Panel_ST7701::init(bool)
• remove Panel_ST7701_guition_esp32_4848S040::init(bool)

Great point, i added Panel ST7701 base initialization. Tks
