hi
buffershift only seems to shift 1 byte, but not the whole buffer:

Testcode:
`const BufferShift = require('buffershift');

rotate();

function rotate(){
var bufLen = 2;
var buf = new Buffer(bufLen);
buf[0] = 0x01;
for (var k = 0; k < bufLen * 8; k++){
console.log(k + '. Iteration with : ' + buf.toString('hex'));
BufferShift.shl(buf, 1);
}
}`

Result:
`0. Iteration with : 0100

1. Iteration with : 0200
2. Iteration with : 0400
3. Iteration with : 0800
4. Iteration with : 1000
5. Iteration with : 2000
6. Iteration with : 4000
7. Iteration with : 8000
8. Iteration with : 0000
9. Iteration with : 0000
10. Iteration with : 0000
11. Iteration with : 0000
12. Iteration with : 0000
13. Iteration with : 0000
14. Iteration with : 0000
15. Iteration with : 0000
    But expecting:0. Iteration with : 0001
16. Iteration with : 0002
17. Iteration with : 0004
18. Iteration with : 0008
19. Iteration with : 0010
20. Iteration with : 0020
21. Iteration with : 0040
22. Iteration with : 0080
23. Iteration with : 0100
24. Iteration with : 0200
25. Iteration with : 0400
26. Iteration with : 0800
27. Iteration with : 1000
28. Iteration with : 2000
29. Iteration with : 4000
30. Iteration with : 8000`

kind regards
