Cleanup after splitting into two packages (#386)
* Move PosterWithAudio to FFMpegCore

* Reduce windows only tests

* Update Directory.Build.props

* Create .editorconfig

* More cleanup

* Enable implicit usings

* Remove unused method

* Apply dotnet format

* Fix unused variable in AudioGateArgument

* Fix boolean conditions in AudioGateArgument

* Merge boolean conditions into pattern

* Use target-typed new

* Add linting to CI

* Add CUDA to HardwareAccelerationDevice enum

* Increase timeout for Video_Join_Image_Sequence

* Adjust Video_Join_Image_Sequence timeout

* Fix expected seconds in Video_Join_Image_Sequence

* Increase timeout for Video_TranscodeToMemory due to macos agents
