Add hint (comment) for using example with Pico and Pimoroni 11x7 LED Matrix Breakout.
1) Pico does not have dedicated pin of I2C, but many board use SCL=GP21 and SDA=GP20
2) Two example assume the width is 15, 16 or 17 but do not look good/centered with a width of 11
( tested with Scroll pHAT HD (17x7) both normal driver but also forcing "width = 11" to see the effect on smaller matrix )
