Allow to use nvenc and nvdec in Windows for nVidia cards.
...
nVidia card don't use the DX API like intel or AMD cards.
If ffmpeg and the libraries are compiled with nvenc and
nvdec support on WIndows this should(!) now work.

Refactor FFmpegWriter Open() and PrepareStreams() methods, so that SetOption() is can be called between them, and allowed to adjust the codecs bit_rate and options before we call open_video(). This was primarily to allow CRF options to work. ( #193 )

* First implementation of CRF (Constant Rate Factor)
* Include AV1 in the codecs that can use crf
* First version that uses SetOption to set crf quality
* Clarify comments
* Delete setting the bitrate for crf in SetVideoOption because it
is not needed, it is set later with SetOptions.
