[LAD] Rubber Band library v1.4 released

[Chris Cannam]

Rubber Band is an audio time-stretching and pitch-shifting library and
utility designed for musical applications. It allows you to change the
tempo and pitch of an audio recording independently of one another.

This maintenance release contains a fix for a hang when faced with
some very peculiar stretch factors, and a fix for some incorrect
threading condition usage.
