Title: adds function StkFrames::copyChannel

signature looks like -
```c++
StkFrames& copyChannel(unsigned int sourceChannel,StkFrames& destinationFrames, unsigned int destinationChannel) const;
```
It copies the specified `sourceChannel` to `destinationFrames`'s `destinationChannel`. Then returns `destinationFrames` This is useful for extracting individual channels of an `StkFrames` object and applying analysis/dsp on them.
