occasional Buffer overflow

[crass00]

Sometimes is get the below error

Assertion failed: coeff % quant == 0, file D:\Work\OpenSource\guetzli-cuda-opencl\guetzli\output_image.cc, line 629

In the below change there is a buffer overflow fix (mixed in with some other stuff)

https://github.com/winsoft666/guetzli-cuda-opencl/commit/6b5a607a91150c6fe7310f5518012b8a78ef3f04#diff-7ae0466468c37e899127f650d1fc3e774ad635659403f406fabd10715f6d729e

Any chance its a potentional fix and fix so any chance of merging it and compiling a new verison (I've tried but I've never been able to sucessfully compile a cuda-opelcl build of this :( )
