PIXB File format

Basic structure

struct PIXBFile:
    struct Header:
        char[4]  = "PIXB"
        uint16_t unknown
        uint32_t Version (?)
        uint16_t Canvas size
        uint32_t unknoxn
        char[16]: unknown

    char[928]: data

Each pixels is stored in a 7 bit packed format which allow to store 8 pixel in 7 bytes:

bit 56-50	bit 49-43	bit 42-36	bit 35-29	bit 28-22	bit 21-15	bit 14-8	bit 7-0
pixel 7	pixel 6	pixel 5	pixel 4	pixel 3	piexl 2	pixel 1	pixel 0

Only value between 0 and 99 are valid, the palette only have 100 entry, all value equal or higher to 100 are considered to be color 0

Also, the file is always the same size and always contain enough space to store the 32x32 size.

If the image is using a 16x16 canvas or 24x24 canvas, the start of the image is shifted by a couple of pixels

Canvas size can take only 3 values:

0: 16x16 canvas
1: 24x24 canvas
2: 32x32 canvas
