/*
* A "fork" of the simple clock face, which provides the functionality of showing
* the current time by flashing the LED using binary representation.
*
* This feature serves as a practical solution to compensate for the admittedly
* subpar backlight of the F91w watch and is especially useful if your eyesight
* is not the best. By pressing and holding the light button long enough, the
* watch will illuminate the LED to showcase the current time.
*
* How to interpret the flashing led:
* - Firstly, the hour is presented as a binary number, with the lowest bit displayed
* first. A short flash signifies 0, while a longer flash represents 1. If you use
* the watch in 24h mode, please note that the indicated value may be decreased
* by 12, to keep things simple and short. For example, 22h would be translated
* to 10h.
* - After showing the hour, a lengthier pause indicates that minutes will be shown
* next.
* - Similar to the hour representation, minutes are displayed in binary format,
* starting with the lowest bits. A short flash denotes 0, a longer flash
* represents 1.
