Add 4bit images to sprites, with an example and a tool to produce the images from bmp files.

Avoid coordinate optimisation for sketch controlled multiple TFT displays. Add #define MULTI_TFT_SUPPORT
to prevent setAddr optimisation that relies on coordinate transfer minimisation.

See new #define options in "Setup29_ILI9341_STM32.h"

Read_User_Setup now includes backlight settings

4bpp Sprites can now be pushed to the TFT with a rotation

See #618

pushRect() reinstated to pair with readRect() so swapBytes does not need to be changed from true to false before calling.

dmaBusy() checks and is no longer blocking
pushImageDMA() faster if setAddrWindow is not built into transaction list.

DMA test examples now work on ESP32

Fix: Font7srle  Character '1' is missing two dots.

TFT_eFEX also needs updating so Rotated_Sprite_3 example renders correctly.

pushImage for FLASH images updated so partly off-screen images are correctly rendered.

See #499

Read_User_Setup updated to be compatible with STM32 and new structure format.
Reduction in compiler warnings
Update Sprite destructor
Update version to 2.2.1

Sprite scroll function fixed for 1bpp
readPixelValue() updated

Performance of circle drawing functions improved.

Version raised to 2.2.0

STM32F1xx processors do not have MODER direction configuration.
