Write a function that takes a binary number as an input and shifts each bit by one to the right or left while looping on itself like a circle.
Make a delay of one second between each shift.

Input : 00101100

Output: (shifting to the right)
First loop: 00010110
Second loop: 00001011
Third loop: 10000101
