b654431d6f Even more direct writes for writePixels on RP2040 
Switch SPI to 16-bit for little-endian, write bytes as-is for big-endian

a3bf8baeee Call spi_write_blocking directly for RP2040 
This is around a 6-13x speed up in graphicstest (at 62.5Mhz)

6d513193e6 Fix two compiler warnings. (#259) 
* Fix compiler warning [-Wunused-const-variable=]

Compiling a sketches that uses this library can report a warning
about the const variable `font` being defined, but never used.
Work around this by defining a (static inline) function which
references the variable.

* Remove unused variable (compiler warning)

0e92646066 Teensy T4.0 support (#232) 
The Teensy T4 (__IMXRT1062__) port registers need to be 32 bits unlike the Teensy 3.x which are 8 bits.

adafruit_ili9341  and adafruit_st7735 libraries graphic test

Removed compiler warning

that PROGMEM was previously defined.  So undefine it first...

Note: Thought of simply doing nothing here
(do neither the #undef nor the #define).

But that gives compiler error

Teensy T4 - Make Bit Bang version work.

With T4, the Port/Set registers are masks not single value.

So need to setup those class variables:

Also found that bitbang of T4, was too fast for display, so put in same slow
down that ESP32 has, which gets the clock down to mayby 12.5mhz

Tried these changes out with both:
adafruit_ili9341  and adafruit_st7735 libraries graphic test
