MMLLQitch requires floating variable sr

[Louismac]

MMLLQitch requires floating variable sr to be set in the surrounding javascript otherwise it fails. E.g in this example project, there is no real need to make sr and set it to sampleRate, but if its no included then theres errors

as a solution , looking at the listener code line 44 of MMLLQitch.js

self.m_SR = sr;

should be

self.m_SR = sampleRate;
