    For the case where a subsequence of a Bytes object needs to be copied, I was thinking the `subsequence()` method could be used.  For example the following could copy the 1st 255 bytes of `b1` to `dest` starting at offset 1024.
    
    ```java 
    
    byte[] dest = ...
    
    Bytes b1;
    
    b1.subsequence(0,255).copyTo(dest, 1024);
    ```
    
    However, calling subsequence will allocate an intermediate Bytes object.  To avoid this, we could have a method like `copyTo(int sourceOffset,  byte[] dest, int destOffset, int len)` instead of `copyTo(byte[] dest, int offset)`.
