Title: added StkFrames::setChannel

looks like
```c++
void setChannel(unsigned int channel,const StkFrames &sourceFrames,unsigned int sourceChannel);
```
copies the `sourceChannel` of `sourceFrames` into the specified `channel` of self. Useful for people wanted to to use StkFrames as a mixer interface.
