History
Harish Mahendrakar 1fac8cc5fe Updates to odd dimension support. 
Reverted some of the unnecessary changes from commit: f6ef16b0f9

- Restored the format conversion structure prior to f6ef16b0f9
- No need to handle odd stride for 420 and 422 output.
- Dimensions for output format 444 and 400 format can be odd

Tested with few YUV444 and YUV400 odd dimension clips

To generate:
$ ffmpeg -f lavfi -i testsrc=s=511x511 -c:v libx265 -pix_fmt yuv444p -t 1 -tag:v hvc1 y444_511x511.hevc
$ ffmpeg -f lavfi -i testsrc=s=511x511 -c:v libx265 -pix_fmt gray -t 1 -tag:v hvc1 y400_511x511.hevc

To decode using hevcdec for YUV420 output format
$ hevcdec -i y444_511x511.hevc -o y444_511x511.yuv --save_output 1 --num_frames -1 --chroma_format YUV_420P --enable_yuv_format 31
$ hevcdec -i y400_511x511.hevc -o y400_511x511.yuv --save_output 1 --num_frames -1 --chroma_format YUV_420P --enable_yuv_format 31

To decode using hevcdec for YUV444 output format
$ hevcdec -i y444_511x511.hevc -o y444_511x511.yuv --save_output 1 --num_frames -1 --chroma_format YUV_444P --enable_yuv_format 31

To decode using hevcdec for YUV400 output format
$ hevcdec -i y400_511x511.hevc -o y400_511x511.yuv --save_output 1 --num_frames -1 --chroma_format GRAY --enable_yuv_format 31

Display resulting output using ffplay by passing `-f rawvideo -pixel_format yuv420p -video_size 511x511`
Change pixel_format to yuv420p/yuv444p/gray based on decoder chroma_format argument
