current pixel, this index position is written to the stream as QOI_OP_INDEX.
The hash function for the index is:
index_position = (r * 3 + g * 5 + b * 7 + a * 11) % 64
index_position = (r * 3 + g * 5 + b * 7 + a * 11) % 64
Each chunk starts with a 2- or 8-bit tag, followed by a number of data bits. The
bit length of chunks is divisible by 8 - i.e. all chunks are byte aligned. All

The colorspace in this qoi_desc is an enum where
0 = sRGB, i.e. gamma scaled RGB channels and a linear alpha channel
1 = all channels are linear
0 = sRGB, i.e. gamma scaled RGB channels and a linear alpha channel

You may use the constants QOI_SRGB or QOI_LINEAR. The colorspace is purely
informative. It will be saved to the file header, but does not affect
en-/decoding in any way. */
