Waveshare 2.1 esp32-s3 display support

Been messing with this trying to get it to work.

I get the backlight to turn on. LOL. But stuck with just getting hello world.

What I updated:

` Arduino_ESP32RGBPanel rgbpanel = new Arduino_ESP32RGBPanel( 40 / DE /, 39 / VSYNC /, 38 / HSYNC /, 41 / PCLK /, / RGB control pins / 5 / B1 /, 45 / B2 /, 48 / B3 /, 47 / B4 /, 21 / B5 /, / Blue pins / 14 / G0 /, 13 / G1 /, 12 / G2 /, 11 / G3 /, 10 / G4 /, 9 / G5 /, / Green pins / 46 / R1 /, 3 / R2 /, 8 / R3 /, 18 / R4 /, 17 / R5 /, / Red pins / 1 / hsync_polarity /, 50 / hsync_front_porch /, 8 / hsync_pulse_width /, 10 / hsync_back_porch /, / Horizontal timings / 1 / vsync_polarity /, 8 / vsync_front_porch /, 3 / vsync_pulse_width /, 8 / vsync_back_porch /, / Vertical timings / 1 / pclk_active_neg */ );

Arduino_RGB_Display gfx = new Arduino_RGB_Display( 480 / width /, 480 / height /, rgbpanel, 0 / rotation /, true / auto_flush */ );

`

Thank you!
