Module zigzag 

Holds helpers for encoding and decoding numbers using the zigzag encoding.

The zigzag encoding converts signed integers to unsigned integers and vice versa.

• Positive signed integers are multiplied by 2.
• Negative signed integers are multiplied by -2 and 1 is subtracted.
• The final result is then converted to an unsigned integer.
