TFT ST7735 example to draw an FFT from audio on an S32K144.

Bugs still exist in TFT fonts.

  SOURCES

  This library has been derived from the Adafruit_GFX
  library and the associated driver library.

  This was also taken and refactored from Github:
  Bodmer / TFT_ST7735
  https://github.com/Bodmer/TFT_ST7735

  TFT graphics library for any uC or SoC with open
  implementations on SPI callbacks.

  No specific HW implementations are available.

  This means: no dependency on Arduino, yay!

  New implementation was brought back from C++ to C
  for more compatibility on more environments.

  Code cleanup and reordering was also applied.
