6.0.0

[bajankristof]

Breaking Changes:

• Changed FFMPEG::IO to use UTF-8 encoding instead of ISO-8859-1 by default
• Changed FFMPEG::Transcoder#run to raise FFMPEG::Error if FFMPEG exits with non-zero exit code even if validate was set to false on the transcoder
• Removed the errors attribute of FFMPEG::Transcoder

Improvements:

• Changed FFMPEG::IO to handle carriage returns by FFMPEG – progress reports will be more frequent and more reliable
• Changed FFMPEG::Transcoder to report progress only on whole percentages by default (e.g.: 0.01, 0.2 etc.)
• Added new progress_digits kwarg to FFMPEG::Transcoder to allow more frequent progress updates
