Lost half day on figuring out how to debug/ print floats :/

There’s a mention of this in this post: SSD1306 OLED compatibility? - #12 by shensley

But printing floats without adding bloat to the firmware makes use of the FMT_* macros:

float f = 3.14;
hardware.PrintLine("Floating point value " FLT_FMT(3), FLT_VAR(f));
//                 |----- output  format string -----| |-- args --|
