Bump to 0.2.6
I added the possibility to convert raw audio files and buffers with the convert node. For this to work you need to include the necessary audio header information that sox needs to process raw audio as msg properties. The format of this is described in the nodes info panel. This can also be used to add wav headers or process raw audio to be played by the play node by routing it through the convert node first.
I will look to publish the node to npm before the end of the year.
