Fixing overflow issue on extreme colors in color_distance(). Explicitly disabling unaligned addressing in miniz and transcoder when UBSAN is enabled Disabling a needless optimization in transcoder causing ubsan issues (that could have easily been worked around in a different way, but it was an unnecessary optimization to begin with) Rebuild wasm builds
