API
##### constructor
var lcd = new CharLCD(params);
params is an object with the following keys:
- at: a DOM element in which to place the object, or its id;
default: at the bottom of the page;
- rom: jp (default) for Japanese standard font, or eu for European standard font.
- rows: - number of rows;
default: 2;
- cols: - number of columns;
default: 16;
Unlike the real hardware where only certain combinations of rows/cols exist, there are no restrictions in the simulator;
##### char(r, c, h)
lcd.char(r, c, h); - set the character at row r, column c to byte h.
##### text(r, c, s)
lcd.text(r, c, s); - print string s at row r, column c.
This function treats \n as new line and maps UNICODE characters to the internal character set.
##### font(n, data)
lcd.font(n, data); - define the pixels for the n-th character; data` is an array of up to 10 bytes.
