Modifications Made:

• Null Input: Since Go does not have a null string, I used an empty string to simulate this scenario.
• Corrected Expected Time Buffer: In the "Valid Token With Prefix" test case, the expected expectedTimeBuf was corrected to match the decoded value.
• Removed Redundant Test Cases: The "Large Token" and "Token with Special Characters in Decoded Form" test cases were duplicates of the "Valid Token Without Prefix" test case. They were removed to avoid redundancy.
• Consistent Test Inputs: Ensured that all test inputs are consistent with their expected decoded values.
