release version 0.7.0

- API:
    - add `Player.setProperty()`
    - add `VideoFrame` class
    - add `Player.onFrame()` to get decoded frame, can be used by custom filters
    - support `MediaStatus::Seeking`
    - add snapshot [MediaEvent](https://github.com/wang-bin/mdk-sdk/wiki/Types#class-mediaevent)
    - `seek()` callback parameter is -2 if seek request is ignored
- ABI: no break
- `setBackgroundColor()`: if alpha is 0(default), you have to call `glClearColor`(or d3d11 api) manually.
- Add FindMDK.cmake in sdk lib/cmake dir, support multiple target architectures.
- Fix multiple D3D11 renderer crash
- Fix crash if audio device is not available
- Fix music with cover buffering progress error
- Fix last frames not rendered if prepare() from a position closed to end of stream.
- Player.setVideoSurfaceSize(-1, -1) can remove the renderer
- prepare() starts from 0 if requested start position > stream duration or duration is unknown
- Improve A-B loop if B is closed to or larger than end of file
- Fix block if A-B loop restarts when previous seeking is not finished
- Music with cover art: fix png not rendered. fix block if stop by user.
- Seek:
    - Fix SeekFromNow
    - Fix audio file read error after seek
    - When end of stream decoded and in paused state
    - Fix seek never work if previous seek failed
    - position() never change after a seek error or a frequent seek request
- snapshot: fix msvc crash
- OpenGL:
    - Save and restore blend states
    - Skip loading EGL if context is not created by mdk
- FFmpeg:
    - support avfilter complex filters via Player property ["video.avfilter" and "audio.avfilter"](https://github.com/wang-bin/mdk-sdk/wiki/Player-APIs#void-setpropertyconst-stdstring-key-const-stdstring-value)
    - Optimize audio filter if in/out parameters are the same
    - Improve video encoder
- VT decoder:
    - Fix the last frame not rendered
    - Support AnnexB streams
- Reduce exported classes
- Fix crashes, memory leaks in stress tests.
- Metal renderer: WIP
- Audio encoder: WIP

-## FFmpeg Runtime Lookup
-FFmpeg modules can be specified via environment var AVUTIL_LIB, AVCODEC_LIB, AVFORMAT_LIB, AVFILTER_LIB, SWRESAMPLE_LIB, SWSCALE_LIB, or SetGlobalOption() with key avutil_lib, avcodec_lib, avformat_lib, swresample_lib, swscale_lib, avfilter_lib. For example `SetGlobalOption("avutil_lib", "/opt/lib/libavutil.so.56")`
-
-If ffmpeg any module is not set, it's searched in the following order
-- current module dir > framework dir(apple) > system default search dir
-- single ffmpeg library w/ version > single ffmpeg library w/o version > ffmpeg modules w/ version > ffmpeg modules w/o version
