    Write base64 decoded data. If necessary, the implementation should accumulate the data in a buffer before writing it to the underlying stream. The maximum number of bytes passed to this method in a single call is 3.
    
    Parameters:
    
    b - the byte array containing the data to write, starting at offset 0
    
    len - the number of bytes to write
    
    Throws:
    
    IOException - if an I/O error occurs
