help
Enable driver for TM (Shenzhen Titan Micro Elec) TM1637 7-segment LED display.
This driver supports 4-digit 7-segment displays commonly found in clock modules
and simple numeric displays.

The TM1637 uses a two-wire serial interface (CLK and DIO) and can control up to
4 digits with brightness control.

This driver implements the auxdisplay API, allowing generic display usage.
Helper APIs for direct number display are also available.
