W8BH clock with EU option

The TFT GPS clock with touch control which has been designed by Bruce E. Hall, W8BH, is a very nice clock with a large and easily readable 3.2" color display. Its three different screens have been nicely laid out and designed also. The processor is an STM32 Blue Pill.

I cloned the software and modified it in two simple ways:

1. EU option

This is a backwards compatible version which can be Europeanized with formats for date and units. It also has possibility for removing the display of the battery icon, when running from a USB supply.

New boolean variables to set:

• US_UNITS - if false: m, kmh, Little-endian date with '.', if true: feet, mph, Middle-Endian date with '/'
• BATTERY_DISPLAY - true: as original code, false: no display of battery icon and status
