Support for LOGO display 10x4

[deHarro]

Hi Francisco!

I use some of those LOGO displays offered by Pollin here in germany as HB10401 (see https://www.pollin.de/p/lcd-modul-hb10401-4x10-121148).
The application I use one of it is described on my hompage.
(It's written in german. At the bottom of the page I added a translation feature (Google translate)).

To get your library up and running with those displays, one has to add a few lines of code in "LCD.cpp" to make the cursor positioning follow the somewhat different screen layout of the HB10401:

// 2017.10.18 deharry - add support for SIEMENS LOGO display, 10x4 chars (see "row_offsetsSpecial")
...

void LCD::setCursor(uint8_t col, uint8_t row)
{
   const byte row_offsetsDef[]   	= { 0x00, 0x40, 0x14, 0x54 }; // For regular LCDs
   const byte row_offsetsSpecial[]	= { 0x00, 0x40, 0x0A, 0x4A }; // For LOGO Display	<<< add this line
   const byte row_offsetsLarge[] 	= { 0x00, 0x40, 0x10, 0x50 }; // For 16x4 LCDs

   if ( row >= _numlines )
   {
	  row = _numlines-1;    // rows start at 0
   }

   // 16x4 LCDs have special memory map layout
   // ----------------------------------------
   if ( _cols == 16 && _numlines == 4 )
   {
	  command(LCD_SETDDRAMADDR | (col + row_offsetsLarge[row]));
   }
   // LOGO Display (10x4) has special memory map layout						<<< add this line
   else if ( _cols == 10 && _numlines == 4 )	// LOGO Display					<<< add this line
   {												<<< add this line
	  command(LCD_SETDDRAMADDR | (col + row_offsetsSpecial[row]));				<<< add this line
   }												<<< add this line
   else
   {
	  command(LCD_SETDDRAMADDR | (col + row_offsetsDef[row]));
   }
}

You may add these lines to your lib to support this sort of displays out of the box.
Thanks!
