Row Offset for 16x4 lcd is wrong

[TilTisback]

Hello,

the row offset in "LiquidTWI2.cpp" line 347 is wrong.

LiquidTWI2/LiquidTWI2.cpp

Line 347 in 30aa480

int row_offsets[] = { 0x00, 0x40, 0x14, 0x54 };

when you compile it with a 16x4 LCD you get this: (im just filling all the characters with 0-15 in hex)

when you change the row offset to
int row_offsets[] = { 0x00, 0x40, 0x10, 0x50 };
you get this like expected:

i think noone has found this bug yet, because i am using a 16x4 LCD instead of a 16x2 LCD.

this fix is wrong, it only transfer the problem that was on the 16x4 screen to the 20x4 ones. There should be 2 distinct offset based on the width of the lcd
