This function generates 30 random walks with 100 steps each and pivots the
result into a long format tibble.
Details
The function generates random walks using the normal distribution with a
specified mean (mu) and standard deviation (sd).
Each walk is generated independently and stored in a tibble. The resulting
tibble is then pivoted into a long format for easier analysis.
