Add n64texconv and bin2c tools to convert extracted .png and .bin to C arrays during build (#2477)

Browse source 
* n64texconv and bin2c

* mv tools/n64texconv tools/assets/

* fix

* more light fixes

* Silence -Wshadow for libimagequant

* Add reference counting gc for palette objects in python bindings

* Fix missing alignment in n64texconv_*_to_c functions

Co-authored-by: Dragorn421 <Dragorn421@users.noreply.github.com>

* Check palette size in n64texconv_image_from_png

* accept memoryview as well as bytes for binary data

* minimal doc on n64texconv_quantize_shared

* fix a buffer size passed to libimagequant

* assert pal count <= 256 on png write

* Disable palette size check for input pngs, ZAPD fails the check

* No OpenMP for clang

* When reading an indexed png into a CI format, requantize if there are too many colors for the target texel size
