aubio/aubio: 0.4.6

Version 0.4.6 includes: yinfast, a new version of the YIN pitch detection algorithm, that uses spectral convolution to compute the same results as the original yin, but with a cost O(N log(N)), making it much faster than the plain implementation (O(N^2)) Intel IPP optimisations (thanks to Eduard Mueller), available for Linux, MacOS, Windows, and Android improved support for emscripten (thanks to Martin Hermant), which compiles the aubio library as a javascript module and lets you run aubio's algorithm directly from within a web-page. 0.4.6 also comes with several bug fixes and improvements. Many thanks to Eduard Mueller (@emuell), Martin Hermant (@MartinHN), Hannes Fritz (@hztirf), Stuart Axon (@stuaxo), Jörg (@7heW4yne), ssj71 (@ssj71), Andreas Borg (@borg), Rob (@mlrobsmt) and everyone else for their valuable contributions and input.
