Add palette encoding to libdvi, plus example (#8) 
* Add palette encoder

(cherry picked from commit c30692ee75b8a2e3aaf4d7d5b809c267f9066aed)

* Add full resolution Mandelbrot as example for palette encoding

* Switch to 2 symbols per word, this is performance neutral on the encode, but saves memory bandwidth

(cherry picked from commit 70834bfa1953a29d95e0d0f5ae16c86d2feb7242)

* Marginally faster palette encode

* Up to 256 colour palettes

(cherry picked from commit 86e0e5d7dd11020d01f167b8cad571391de56aee)

* Apply parity alternation to palette and other full res case

(cherry picked from commit e9971155ff08977275612e4d22d37f0f416ef13e)

* Use 256 colour palette, generate on both cores

* Clear up magic numbers

(cherry picked from commit 6180d210e59f25c7c4b4855920acdaa973447228)

* Use PICO_DEFAULT_LED_PIN

(cherry picked from commit 383c6eb4b6ea79b617d785e3736ea744746f57af)

Luke Wren e6a12a08aa Pico default clkdiv is now 2, so vista doesn't need an increase, but bad_apple needs a decrease 2021-03-04 20:56:54 +00:00
