New issue 1: average bitrate inaccuracy due to 32bit uint

Saob:

The CLIOptions struct in x265.cpp uses a 32bit uint for totalbytes, causing the value to reset to 0 once the encoded file has exceeded ~4.2gb, and therefor making the current average bitrate inaccurate. Changing this to 64bit should fix that.
