Enhance drawLine function with raw buffer possibility

[dschweinbenz]

In order to be able to use different character code pages it is necessary to print the raw hex value of a character from the codepage. With this enhancement it is possible to draw a line using the line character ─ from PC850:

printer.setCharacterCodeTable(2);
printer.drawLine(Buffer.from('C4', 'hex'));
printer.setCharacterCodeTable(0);
