cscd: video with width not multiple of 4 fails to decode

Description
"cscd_1_0_306_306_lzo.avi" file was encoded by the "CamStudio Lossless Codec 1.0"
"cscd_1_5_306_306_lzo.avi" file was encoded by the "CamStudio Lossless Codec 1.5"
camcodec.dll 1.5 is able to decode both of the files correctly.
FFmpeg fails to decode "cscd_1_0_306_306_lzo.avi" file.
What is a reason for this I don't know, but I guess that both files should decode correctly with FFmpeg's decoder just like they do with the original thing.
Also both of the files decodes to identical output when I export them to RAW in VirtualDub: File->Export->Raw video...

Suggested fix: https://lists.ffmpeg.org/pipermail/ffmpeg-devel/2023-March/307262.html
Tests with other width/height could be interressting as the equation is only based on that one sample.

I did some testing with various resolutions and yes, this patch fixes the problem, thanks!
But unfortunatelly while testing this codec in more detail I found another regression, this time in gzip decompression - ticket #10241.

This is another regression somewhere between 20180614-29cddc9 and 20181029-32d021c:
