* Draws a QR code in the screen
* @param x1 The top left x coordinate to start the QR code.
* @param y1 The top left y coordinate to start the QR code.
* @param content The content of the QR code (as a plain text - Nextion will generate the QR code).
* @param size The size (in pixels) for the QR code. Defaults to 200px.
* @param background_color The background color to draw with (as rgb565 integer). Defaults to 65535 (white).
* @param foreground_color The foreground color to draw with (as rgb565 integer). Defaults to 0 (black).
* @param logo_pic The picture id for the logo in the center of the QR code. Defaults to -1 (no logo).
* @param border_width The border width (in pixels) for the QR code. Defaults to 8px.

* Example:
* ```cpp
* it.qrcode(25, 25, "WIFI:S:MySSID;T:WPA;P:MyPassW0rd;;");
* ```
