BackgroundRemover Files

Fixes

• -mt (mask threshold) is now honored in single-file and pipe modes, matching -if folder mode behavior (#188)
• Matte/mask video output (-mk) is now written at the source resolution instead of 320px inference height, with quality-based encoding (#185)
• Fixed a hang at the end of video processing when the container's packet count overestimated the number of decodable frames
• GUI: import errors are now caught and shown in the error dialog instead of "Failed to process image: None" (#191, thanks @Naji-Ullah)

Other

• Added CONTRIBUTING.md
