Add support for AC057TC1 5.7" panel used on Inkplate 6COLOR.

[JosipKuci]

Add support for the AC057TC1 7-color ACeP panel which is used on the Soldered Inkplate 6COLOR device, along with a define used to pre-configure pins for use with the Inkplate 6COLOR device

Changes

• bb_epaper.h - Added enum EP57_ACEP_600x448 to display types, right before EP_PANEL_COUNT. Added enum EPD_INKPLATE6COLOR to products with built-in EPDs
• bb_ep.inl - Added epd57_acep_init sequence, following the sequence available in the Inkplate Arduino Library, added panel details in the panelDefs array. Added custom ACeP color mapping named u8Colors_7clr_v2, as the panel has a different mapping compared to the basic 7-color ACeP map
• bb_epaper.cpp - Added switch statement for automatically configuring the pins when EPD_INKPLATE6COLOR is selected

Testing

Testing was done with the following Arduino sketch:

#include <bb_epaper.h>
// Use one of the built-in fonts
#include "Fonts/Roboto_Black_24.h"
BBEPAPER bbep;

void setup(void)
{
int rc;

   Serial.begin(115200);
   delay(3000); // give time for USB->CDC to start
   Serial.println("Starting...");
   rc = bbep.begin(EPD_INKPLATE6COLOR);
   if (rc == BBEP_SUCCESS) {
      bbep.allocBuffer(); 
      bbep.fillScreen(BBEP_WHITE);
      bbep.setFont(Roboto_Black_24);
      bbep.setTextColor(BBEP_BLACK);
      bbep.setCursor(0, 40); 
      bbep.println("bb_epaper");
      bbep.setTextColor(BBEP_RED);
      bbep.println("Inkplate 6COLOR");
      bbep.setTextColor(BBEP_BLUE);
      bbep.println("7-color ACeP 600x448");
      bbep.fillCircle(100, 250, 60, BBEP_YELLOW);
      bbep.fillCircle(230, 250, 60, BBEP_GREEN);
      bbep.fillCircle(360, 250, 60, BBEP_ORANGE);
      bbep.fillCircle(490, 250, 60, BBEP_BLACK);
      bbep.writePlane(); // Send the local graphics copy to the EPD memory
      bbep.refresh(REFRESH_FULL); // ACeP panels only support full (slow) refresh
      bbep.wait();
      bbep.sleep(LIGHT_SLEEP);
   } else {
      Serial.println("Panel init failed");
   }
} 

void loop(void)
{
} 

With it producing the following, expected output:
