WaveFile::Writer#close

Closes the Writer. After a Writer is closed, no more sample data can be written to it.

Note that the wave file will NOT be valid until this method is called. The wave file 
format requires certain information about the amount of sample data, and this can't be 
determined until all samples have been written. (This method doesn't need to be called 
when passing a block to Writer.new, as this method will automatically be called when 
the block exits).

Returns nothing.
Raises IOError if the Writer is already closed.
