Rewrites the cursed Pico RGB Keypad code so that it can't hurt anyone else.
Turns out the whole loop could have been a bitwise operator.
The true lesson was the people we met along the way.
Removes all driver-specific SDA/SCL pin definitions and defaults.
Pin type is "uint" everywhere, but "PIN_UNUSED" is *int*_max for MicroPython compat. That's still a lot of pins!
Adds baudrate to the I2C class, and allows a driver (like Trackball) to check the baudrate is supported
This change adds a common I2C class, gathering various I2C functions into a single point of responsibility.
It's necessary for correctly managing the I2C bus pins and state across multiple devices.
* Add a common/pimoroni.hpp to list default pins for various add-ons
* Move the BG SPI Slot enum here for safe keeping
* Switch all GPIO pin references to "uint" to match Pico SDK and bring back PIN_UNUSED as UINT_MAX
Confused myself by plugging this into a BG base. It gave all the appearance of working, but the time was not counting up.
Turns out the library will happily talk to no device whatsoever and when you "set_time" it's stored in an C array and returned as if it came from the RTC.

Move scroll_text into the C++ library and make it support std::string.
Move show_bitmap_1d to set_bitmap_1d in the C++ library. Use it as the basis for show_text and scroll_text.
Change show_text to set_text since it does not implicitly show the result.
Add a new pico-scroll demo to show off the scrolling text functionality.
Add IS31FL3731 driver
Add RGBMatrix5x5 library and example
Add Matrix11x7 library and example

A new constructor has been added which accepts a enum type BG_SPI_SLOT which can be either:
ST7789::BG_SPI_FRONT or ST7789::BG_SPI_BACK.
This selects the correct CS/BL pins for the respective breakout-garden SPI slot.
Additionally the PWM'd backlight is turned *on* by default to avoid any confusion when the user does not set a value.
