qaac

• Fix: https://github.com/nu774/qaac/issues/115 (was a regression on 2.83)
• Add CAF file parser, support FLAC in CAF container.

Switched to a custom input stream reader to address suboptimal I/O performance when reading files, mentioned here: https://hydrogenaud.io/index.php/topic,127609.0.html

• Fixed https://github.com/nu774/qaac/issues/104 (behavior of --artwork-size)
• Added support of some recent CAF channel layout

Enabled Non-Linear adaptive coding enhancer (NoLACE) when (and only when) decoding opus in MP4 container. libopus >= 1.5 built with --enable-osce (which is off by default) is required (binary attached here). Unfortunately, ordinary .opus file is supported only via libsndfile, in which case qaac has no direct control over libopus. Hence only MP4 file is supported.

• Support gapless decoding of MP3 files encoded by iTunes
• Use edts/elst even when movie timescale is smaller than media timescale (although in this case it's impossible to obtain sample accurate duration )
• Support decoding opus in ISOBMFF(mp4)
