Calculate the weight for each face on the constant latitude

[hongyuchen1030]

Describe the feature you'd like added to this project
The function calculates the weights of grid faces at a specific constant latitude, facilitating accurate non-conservative zonal averages in climate and oceanographic data analysis. This addition aims to optimize and simplify user workflows within our library.

Describe the solution you'd like

• Take a constant latitude as input and compute the perimeter of the corresponding circle.
• Identify the intervals of longitude that overlap with each face of the grid.
• Calculate the weight of each face based on these intervals and the total perimeter.
• Handle any errors or edge cases gracefully, ensuring that the function is robust and user-friendly.
