The updates of support for SHVC

[Wilson-Ian]

Hello! I read the discussions and response in threads and noticed that we have a hevc_extension branch which supports SHVC.

Could any expert please help give some hint what the detail difference is between the main branch hevc_rext and this extension branch? Do we have any plan to update for SHVC support? Thanks!

And one more question is:
I disable lots of Marcros and related code for non-x86 platform so that i can compile and link the lib successfully on windows x64 vs2019. But I'm not sure my operations are valid or not even though the demo command works. Do we have any schedule to update the solution setup as professional reference for windows if possible? Thanks again!
