Add method to change buffer size

[rjgriffin42]

It's impossible to figure out how to change the buffer size from code. You can set hte buffer record period, and you can get the buffer size, but you should just have a scs.setBufferSize(int) method.

There is a setter but pattern matching SCS1 for the name it's called changeBufferSize(int). I suppose I look into simplify the method names.
